How to enable Task Manager?
Click Start goto Run, type gpedit.msc and click OK. Navigate to this branch:
User Configuration / Administrative Templates / System / Ctrl+Alt+Delete Options / Remove Task Manager
Double-click the Remove Task Manager option. Set the policy to Not Configured
Use regedit to open the Registry Editor and locate the following key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System.Find the DWORD value named Disable TaskMgr and set it to 0 or delete it altogether
This will make the Task Manager available again, although you might need to log off for the changes to take effect.
This same process can be used to disable the Task Manager, but you might have to create the registry key System under the Policies key. After creating the System key, create a new REG_DWORD (DWORD value) named Disable TaskMgr and set the data value to 1.

LAN is not working!!!!!!!
If LAN is not working there may be few reasons behind it.
First check whether your Network adapter is working properly or not.
Right click on My computer Icon Then properties then hardware then device manager then see for network adapters within that see whether ur network adapter is working or not.if it is disabled,enable it.
Then install the driver for ur network adapter which is present on your laptop's provider site.

which antivirus and how to configure, to protect my lan including all the 8 comps attached to it?
ZoneAlarm Anti-Spyware will work on any LAN connection with firewalls and proxies. Typically, no additional configuration is needed for ZoneAlarm to work on a LAN.
Making your computer visible on your local networkIf you cannot see the other computers on your local network, or they cannot see you, it is possible that ZoneAlarm Anti-Spyware is blocking the NetBIOS traffic necessary for Windows network visibility. To make your computer visible to the others on your local network:
Add the network subnet (or, in a small network, the IP address of each computer with which you're sharing the network) to your Trusted Zone.
Set the Trusted Zone security level to Medium, and the Internet Zone security level to High.
This configuration allows trusted computers to access your shared files, but blocks all other machines from accessing them. Note: ZoneAlarm Anti-Spyware will detect your network automatically and display the New Network alert. You can use the alert itself to add your network subnet to the Trusted Zone. Sharing files and printers across a local networkTo configure ZoneAlarm Anti-Spyware for secure sharing:
Add the network subnet (or, in a small network, the IP address of each computer with which you're sharing the network) to your Trusted Zone.
Set the Trusted Zone security level to Medium. This setting allows trusted computers to access your shared files.
Set Internet Zone security level to High. This setting makes your computer invisible to non-trusted machines.
Note: ZoneAlarm Anti-Spyware will detect your network automatically and display the New Network alert. You can use the alert itself to add your network subnet to the Trusted Zone. Internet Connection Sharing (ICS)If you are using Windows' Internet Connection Sharing (ICS) option, or a third-party connection sharing program, you can protect all of the computers that share the connection from inbound threats by installing ZoneAlarm Anti-Spyware on the "gateway" machine only. However, to receive outbound (Program Control) protection, or to see alerts on the client machines, you must have ZoneAlarm Anti-Spyware installed on each client machine as well. Tip: Before you configure ZoneAlarm Anti-Spyware, use your ICS software to set up the gateway and client relationships . If you use hardware such as a server or router, rather than a host PC, to perform Internet connection sharing, do not follow the steps below. On the ICS gateway machine:
Go to Main tab of the Firewall panel.
Click Advanced.
Under Internet Connection Sharing, select This computer is an ICS gateway.
In the combination box, select or type the IP address of the gateway machine.
Select Suppress alerts locally if forwarded to clients if you do not want to see alerts that are forwarded to a client.
Note: That if you do not install ZoneAlarm Anti-Spyware on the client machines, all alerts will be displayed on the gateway. For best security, make sure the security level for the Internet Zone is set to High. Make sure outgoing DNS and DHCP are allowed for the Internet Zone at High security. On the ICS client machines:
Go to Main tab of the Firewall panel.
Click Advanced.
Under Internet Connection Sharing, select This computer is a client of an ICS gateway running ZA Pro.
In the combination box, select or type the IP address of the gateway machine.
Select Forward alerts from gateway to this computer if you want alerts occurring on the gateway machine to be displayed on this client.
If Connecting through a proxy server
To enable your computer to connect to the Internet through a proxy server, add the proxy to your Trusted Zone
But if you want all three in one then use ZoneAlarm Internet Security Suite, which integrates anti-virus, anti-spyware and a firewall.

To configure WPA for powerful encryption :
Configuring WPA wireless security on the router
First, let's log on to the router.
Open your internet browser and type http://192.168.1.1 in the address bar. This is the default IP address of the browser.
In the login box that appears type 'admin' (without quotes) in both fields. 'admin' is the default username and password.
Write down the SSID
In the Wireless > Basic Wireless Settings menu you will see the Service Set Identifier or SSID. The SSID differentiates one wireless network from another. It is the 'network name'. Write it down, or copy paste it to a text file. You will need it later. You can first set your own SSID if you like.
In the Linksys WRT54G router you will find the wireless security options under Wireless > Wireless Security. This page allows you to set wireless encryption options.
Set the WPA alghoritm to TKIP.
Type a key in the WPA Shared Key field with a length between 8 and 32 characters. Remember that a longer key is more secure. Besides that, a key that is made up of random characters is harder to crack than a key that contains real words, because real words can be guessed far easier.
Write down the key or copy-paste to a text file, because you will need it later to connect to the network.
Click Save Settings
Your computer will now be disconnected from the router. You may see a 'page not found' warning or some other error message in your webbrowser. Your router now demands that computers that connect to it use WPA encryption and the correct WPA key. In other words: you have succesfully secured your network. Now let's configure your computer to reconnect to the router using the right WPA key.
Configuring WPA security in Windows XP SP2
I will show you how to configure WPA using Windows' built-in wireless network options. Most wireless network card manufacturers create have developed their own configuration software that you can use to manage wireless connections and security. You can use whichever software you like best. The settings remain the same. Please note that you will need a computer with a properly installed wireless network card to continue.
1.In Windows XP go to Start > Settings > Network Connections.
2.Doubleclick the wireless network connection. The wireless network connections window will appear. This window shows you the wireless networks that are within range.
3.If all is right than you should see your wireless network in the list, since your router is advertising your network's SSID to the outside world. In this example I used the word 'kazam' as the SSID.
4.Click change advanced settings in the bottom-left corner of the window. A new window will appear. Select the wireless networks tab.
5.Select your network's SSID from the list and click the properties button. This will bring up the window that allows you to fill out the network key.
6.Select WPA-PSK from the Network Authentication dropdown and select TKIP from the Data encryption menu.
7.Type or rather paste your network key in both the network key fields at the bottom.
8.Click OK.
Your computer should now reconnect to the router using WPA wireless security and the proper network key. You can consider your network well secured now.

How to encrypt data on lan (i m already using it password protected/authorised)?
write your query clearly.There are different kinds of encryption but what type of it, is required by you? Anyways here it goes and tell if it helped or not by posting comment on the site so that i can help further. you have to read these things because i dont know which encryption are you using WEP or WPA.
KEY POINT to prevent misuse of WiFi Facility by unauthorized user, ALWAYS USE Security feature of WiFi router given above and repeated below again:
SSID : The SSID is a unique name to identify the ADSL Router in the wireless LAN. Wireless clients associating to the ADSL Router must have the same SSID.
Broadcast SSID Select No to hide the SSID such that a station can not obtain the SSID through passive scanning. Select Yes to make the SSID visible so a station can obtain the SSID through passive scanning.
Wireless LAN :: WEPWEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network. Select Disable to allow all wireless computers to communicate with the access points without any data encryption.Select 64-bit WEP or 128-bit WEP to use data encryption.Key#1~Key#4 The WEP keys are used to encrypt data. Both the ADSL Router and the wireless clients must use the same WEP key for data transmission.If you chose 64-bit WEP, then enter any 5 Characters each key (1-4). If you chose 128-bit WEP, then enter 13 characters for each key (1-4).The values must be set up exactly the same on the Access Points as they are on the wireless client stations. The same value must be assigned to Key 1 on both the access point (your ADSL Router) and the client adapters, the same value must be assigned to Key 2 on both the access point and the client stations and so on, for all four WEP keys.
Wireless LAN :: WPA-PSKWi-Fi Protected Access, pre-shared key. Encrypts data frames before transmitting over the wireless network.Pre-shared Key The Pre-shared Key are used to encrypt data. Both the ADSL Router and the wireless clients must use the same WPA-PSK key for data transmission. Key Length 8 – 64 characters.
Wireless LAN :: MAC FilterYou can allow or deny a list of MAC addresses associated with the wireless stations access to the ADSL Router.Status Use the drop down list box to enable or disable MAC address filtering.Action Select Deny Association to block access to the router, MAC addresses not listed will be allowed to access the router. Select Allow Association to permit access to the router, MAC addresses not listed will be denied access to the router.

Say no to WEP & use WPA:
Back when the first consumer WLAN hardware hit the streets more than six years ago, they came with a technology called WEP, or wired equivalent privacy
WEP was designed to protect a wireless network from eavesdropping, but it soon became apparent that due to myriad flaws, WEP's privacy was not at all equivalent to that of a wired network. Therefore, it wasn't long (though at the time it seemed like forever) before a new technology called WPA — Wi-Fi Protected Access — debuted to address many of WEP's shortcomings.
WPA has been a mainstream technology for years now, but WEP remains a standard feature on virtually every wireless router on store shelves today. Although it's mainly there for backward compatibility with the oldest hardware, if reports and studies are accurate, a significant percentage of WLANs operating today (especially those used in homes) are still using outdated and insecure WEP for their encryption.
Widespread use of WEP is almost understandable given that to the layperson, the similar abbreviations WEP and WPA don't convey any meaningful difference between the two security methods (and they may even imply equivalence) Plus, WEP is almost always presented first by the security interface of most broadband routers since WEP comes before WPA both historically and alphabetically).
This week we'll take a look at why you shouldn't be using WEP anymore, and why WPA is a better choice.
WEP — The Weak Encryption Protocol
WEP's major weakness is its use of static encryption keys. When you set up a router with a WEP encryption key, that one key is used by every device on your network to encrypt every packet that's transmitted. But the fact that packets are encrypted doesn't prevent them from being intercepted, and due to some esoteric technical flaws it's entirely possible for an eavesdropper to intercept enough WEP-encrypted packets to eventually deduce what the key is.
This problem used to be something you could mitigate by periodically changing the WEP key (which is why routers generally allow you to store up to four keys). But few bother to do this because changing WEP keys is inconvenient and time-consuming — it has to be done not just on the router, but on every device that connects to it. As a result, most people just set up a single key and then continue using it ad infinitum.
A recent development reinforces how even changing WEP keys frequently is no longer sufficient to protect a WLAN. The process of "cracking" a WEP key used to require that a malicious hacker intercept millions of packets plus a fair amount of time and computing power.
But technology moves fast, and that's no longer the case. In fact, researchers in the computer science department of a German university recently demonstrated the capability to compromise a WEP-protected network very quickly. After spending less than a minute intercepting data (fewer than 100,000 packets in all) they were able to compromise a WEP key in just three seconds, and they did it using a system equipped with a mere 1.7 GHz Pentium M CPU, which is less powerful than the processor found in today's entry-level notebooks.
Of course, none of this means that there's necessarily someone lurking outside your window with the capability or desire to hack your wireless network in the blink of an eye. But given that it can be broken increasingly easily with commonly available equipment and software.
*** Important***
Switch to WPA
Even if your router is several years old, it almost certainly supports some form of WPA (and if it doesn't, upgrading to the latest firmware may fix that). The easiest-to-use and most widely supported version is WPA Personal, sometimes referred to as WPA Pre-Shared Key (PSK).
To encrypt a network with WPA Personal/PSK you provide your router not with an encryption key, but rather with a plain-English passphrase between 8 and 63 characters long. Using a technology called TKIP (for Temporal Key Integrity Protocol), that passphrase, along with the network SSID, is used to generate unique encryption keys for each wireless client. And those encryption keys are constantly changed. (Although WEP also supports passphrases, it does so only as a way to more easily create static keys, which are usually comprised of the hex characters 0-9 and A-F).
Unfortunately, there are still wireless devices being sold today — mostly of the consumer electronics variety — that don't support WPA. Frankly, you should avoid buying any wireless device that does not support WPA. When it comes to regular PCs, WPA is supported by both Windows XP with Service Pack 2 and Mac OS X (as well as Windows Vista, naturally). In XP you won't find WPA options in the Data encryption drop-down menu found within the properties sheet for a wireless network connection. Look for it instead under Network Authentication, and then make sure that the choice you make for Data encryption — TKIP or AES — matches what your router is set for. (Many routers support AES, which offers stronger encryption that the kind used by TKIP.)
Properly configured, WPA offers you infinitely better protection than WEP.
If your router or its firmware is of relatively recent vintage (within the last 18-24 months), it may support WPA2, which provides further improvements over WPA, including using AES encryption by default.

How to share drives/data on computers via lan (the dialer modem is in the wi-fi device itself, which receives the broadband connection)?
For sharing drives first of all some points must be kept in mind:
1. All the computers in the network must be in same workgroup
2. The drive which contains the file or folder which is to be shared must be shared too! Means to share the lunch box with ur friend, you must open it completely and give full permission to take the bread.Ex: For sharing My document folder first you should share c: drive or the root drive.
1. To configure all computer in the same workgroup on xp:
Right click on the my computer icon from the desktop and select properties.Goto computer name tab Then click on change button against To rename this computer or join a domain,click change. You can provide a unique name to your computer in the computer name box.
After that in workgroup give the name of workgroup say MS office and click ok. This procedure should be applied on all the computers in the network. Provide the same name as MS office to all the computer's workgroup.
After that click on the Remote tab in the system properties window.There you can give permission to those who can remotely connect to your computer on the network. Then click ok.
After that goto My network places and from left hand side click on view network connectios. Then select the LAN through which this computer is in network and right click on it and then properties. In that window goto Internet protocol(TCP/IP) and click on properties and check the ip address is there or not. Because it should be there as your system is already in network. Then click ok.
After this ping every computer on the network with their ip address or computer name( present in my computer> right click properties> computer name>see full computer name.)
For pinging : Goto start> Run> cmd then ok. Come to C prompt or
C:\> Ping ip address or computer name. If all the computers will be on it will display Reply from say 34.67.191.178 ..........
The ping will show you that all the computers are working properly and are in the network.
Then comes the main part drive sharing.
2. To share a drive goto my computer by double clicking on it. Click on the drive which you want to share. Say C: Right click on it and goto Sharing and security Then click on the link If you understand the risk but still want to share the root of the drive,click here.
C: drive properties window will be opened.
Then in the Network sharing and security click on Network Setup wizard.It will take you further and then comes select a connection method. If your computer is the gateway then select first option or if some other computer is the default gateway then select second option else other. But recommended is second option and click next. then you can give description for this computer and can change the name of computer here also. Then workgroup name Ms Office as setup earlier then next.Then you can enable file and printer sharing then next.* Gateway: the first computer in the network having ip: 192.168.0.1 (Recommended)or something else.After that click on fourth option just want to finish. Then it will ask to restart your computer. Restart it.
Then again goto my computer and right click on C: drive sharing and security > go further Then under network sharing and security.Check the box share this folder on the network. you can give any share name which users on other networked computers will use to access this disk or folder. For maximum compatibility with all versions of Windows, use 1-12 characters. By default, users on other computers have full access: they can read, write, and delete shared files. If you only want them to be able to read files, un-check Allow network users to change my files.
Warning: If a user has full access, deleting a file doesn't put it in the Recycle Bin. Once it's deleted, it's gone for good.
3. On every machine you need to disable simple file sharing. Goto my computer then go to Tools -> Folder Options -> View -> and uncheck Use simple file sharing (Recommended).
4. Turn off the Windows firewall.
Restart your computer.
Follow the same steps as above on all computers in the network.
There is no relationship between sharing and wi-fi or wired connection there should be connection either wired or wireless. No relation again with broadband.your internet is working through LAN card but sharing is nothing to do with broadband or dial up or dsl.
To see which computers are in the workgroup goto My network places and view workgroup computers. In my network places you will be able to see all the drives which are shared in the network and can access from there !!!!!!!!!!!!!!!! Work is done successfully! Further assistance would be provided in this regard.
1. All the computers in the network must be in same workgroup
2. The drive which contains the file or folder which is to be shared must be shared too! Means to share the lunch box with ur friend, you must open it completely and give full permission to take the bread.Ex: For sharing My document folder first you should share c: drive or the root drive.
1. To configure all computer in the same workgroup on xp:
Right click on the my computer icon from the desktop and select properties.Goto computer name tab Then click on change button against To rename this computer or join a domain,click change. You can provide a unique name to your computer in the computer name box.
After that in workgroup give the name of workgroup say MS office and click ok. This procedure should be applied on all the computers in the network. Provide the same name as MS office to all the computer's workgroup.
After that click on the Remote tab in the system properties window.There you can give permission to those who can remotely connect to your computer on the network. Then click ok.
After that goto My network places and from left hand side click on view network connectios. Then select the LAN through which this computer is in network and right click on it and then properties. In that window goto Internet protocol(TCP/IP) and click on properties and check the ip address is there or not. Because it should be there as your system is already in network. Then click ok.
After this ping every computer on the network with their ip address or computer name( present in my computer> right click properties> computer name>see full computer name.)
For pinging : Goto start> Run> cmd then ok. Come to C prompt or
C:\> Ping ip address or computer name. If all the computers will be on it will display Reply from say 34.67.191.178 ..........

ssd vs conventional hdd
On the right hand side laptop using ssd and on the left conventional hard drive.
Is there any definite advantage of solid state hard drives as compared to the conventional hdd??
Yes Solid State hard drives are better than conventional one but the demerits are it's very expensive.Read this article and hope you get your answer. See the video too n get your answer to the question.
The SSD drives with SATA interfaces are terrific because they can be used in current laptops with no mods, the real performance of flash memory is only going to be unlocked when we cast aside the legacy of spinning disks and their cases and interfaces and mount SSDs on the mobo like we do RAM modules.
Micron announced that they will be releasing the RealSSD line of solid state drives, including a 64GB drive. While the entire line ranges from 1GB to 64GB, the 32 and 64 GB models are geared toward notebook and desktop use. The drives feature a SATA II interface and draw a mere 2 watts of power.
The best way to explain why SSD is a buzz acronym for the solid state drives we want in our notebooks is to show the problems with practically stone-age spinning hard drives inside most computers (and iPod classics). Since they have platters w/ magnetized surfaces that spin fast as they read or write data—think record player—they can be quite slow, and are really fragile. Anyone who's owned a computer or iPod knows (or will one day learn) that if the read/write head bumps into the platter, it's all over. SSDs aren't like that at all.
SSDs have no moving parts, so seek time is drastically reduced. No spinning=less battery vampirage, so your laptop lasts longer too. And finally, the lack of a deadly read-write head means you can drop your SSD-powered lappy with far less chance of weeping. Right now, SSDs are usually made with either SDRAM (like RAM used in computers) or NAND flash (like in thumb drives, iPod nanos, etc.). Flash is more common, since it doesn't need a battery even though it's slower. Problems: Gig for gig, SSD is way expensive. The beefiest you'll be able to get soon is 128GB (or maybe 256GB)—but the current 64GB 2.5" SSDs go for $1,100 and up.
