I have a Windows 2003 server and around 200 users. I have one teacher who has done the same thing once before and I reloaded everything to fix it but now she has done it again. She can't access the internet from her laptop. The IP address was received along with the correct DNS and etc. I can ping www.yahoo.com but I cannot access any websites. I tried logging in as a a different user and the same thing. I have cleared the history and cache of IE and no luck. No one else is having this problem. Suggestions?

Hello ldunn74,

You could try one of the various TCP/IP fix programs that are around. One I have had sucess with is LSPFix. It's a freebie.

Regards,

Have you tried the Winsock fix? This will often repair the specific problem you mentioned. Usually cased by malware of some sort.

I have disabled IE addons, AV, tried repairing WINSOCK, no luck. If WINSOCK is corrupter wouldnt it block me from pinging web addresses? I can ping fine but can't access. Still trying malware removers. I tried to scan drive for viruses too and it was odd, immediatly said complete when I said scan. We us Symantec Corprate. Anything else you can think of?

Please check symantec on the server. it is possible to that server blocks computer from internet access if client's AV signatures are out of date
