Dear nepali_kanchi: My two cents--- Your problem description is too vague. There can be many different reasons why you can't get into the network. If your network administrators have not blocked you from accessing the network (because you've said you got some access violation notice from the IT department), then most likely, your computer is not set up right. You said you just installed a new anti-virus... Does it have a built in firewall... If it does and is enabled, maybe you are on the network but your firewall is blocking all outgoing connections. Also, make sure your Network Adapter driver is currently installed on the computer. The other place to check would be your TCP/IP settings under Network Connections. If your school/library allows plug-and-play internet connections, then you'll probably want to make sure the TCP/IP settings are configured to use the DHCP (Check where it says "Detect automatically" or somthign like that). If that still doesn't fix it, then please describe your problem in a bit more detail such as: 1. Your operating system 2. Output of the "ipconfig" command (type 'ipconfig' and hit enter on the black command prompt window) 3. Output of your "netstat a/" command 4. Output of your "ping .edu" command 5. Your TCP/IP settings 6. Go to-->Control Panel-->System-->Hardware-->Device Manager On the window that appears, make sure there is no yellow exclamation mark by the 'Network apdpter' section. So as I said, there might be a number of various reasons why can't get onto the network... I would say your best bet is for you to let shaq have a look at it and he'll fix it all for you while you sit back and read/write more kurakani threads on your roomie's computer. Lemme know if you need some influence to get shaq to work on it... :p But if you have backed up your crucial data (such as all the love letters received so far, which you are yet to respond to), and have the re-installation disks, then like gallant said, the ultimate solution is to rebuild the machine.... first back up your data (eg, copy your files onto a CD), then put the Windows reinstallation CD in, then turn the computer off, then turn it back on, and select to boot from the CD and follow the instructions that will appear on a set of blue screens...When asked, you will want to remove the existing system and reinstall all over. Good day! Echoes
