A client computer on our network is having a weird problem. The
Pc can access network resources on the local lan and internet
using all protocols except HTTP. nslookup, ftp, ping (icmp) etc
all work fine.

The PC can access our Intranet website via HTTP, but when trying
to pull up any web pages on the internet IE returns a 404 error
and Netscape gives and error saying the host actively refused the
connection. Again, DNS queries work fine and so does FTP.

Has anyone seen this?? It is quite baffling.

Windows xp services pack 2. Same issue with ie6, ie7 and
netscape. Have disabled personal firewall, anti virus (norton)
with no luck. Tried Wireless ( 3 different networks) and wired
connection with same issue. Seems after rebooting the PC can
access the internet for a few minutes, then the errors begin
occurring.

Any suggestions/Advice


This sounds very much like a firewall problem. Try the following:

1) Uninstall any firewall product on your machine ("disabling" doesn't
always work)
2) Uninstall any VPN Client software you might have installed (they
usually have a firewall function as well)
3) You might try running LSPFix.

4) Try booting in Safe Mode with Networking. If your computer then
works, then something that gets loaded after the basic boot is
inhibiting access. Use a program like AutoRuns to enable/disable
blocks of startup programs until you narrow it down...
