Querky ICS on XP/NT

I have MS-ICS running on windows XP
Clients are
Win98
Linux
NT4.0

all clients were working but suddenly IE5.5 in the NT stopped working. The other clients still work.
On NT:
ipconfig /all looks normal
I can ping internal and external hosts by name/number
I can telnet to extermal and internal hosts
IE can resolve names to addresses but never displays any results. It just times-out.
I also run 'norton anti virus 2001' on it. LiveUpdate fails to connect to Symantec.

netstat -an shows an ESTABLISHED connection to the correct IP address but no results are delivered.

Any ideas? I think it got hacked but I don't know how.
I was working near the system when I noticed alot of disk/network activity going on. When i checked I could not identify the reason for the activity so did a restart.
After the restart -- no IE.

The internet connection comes through the XP box.
PCanywhere is maped via NAT to the NT but it does not show any unexpected connections in the log.

Further symptoms/tests
1. Using RAS to connect to ISP every thing works.
2. Using a Win98 box to connect to DSL and SolidShare software ( NAT/router ) everything works.
3. Using XP to connect to DSL and MS-ICS the Win98 box works, the Linux box works, but the NT box can only get to some web sites. ( I've tried a number of different ones an have ONLY been succesful loading home.netscape.com, Yahoo, Exite, AOL, MSN, Microsoft, my.netscape.com..... other will not download ??????) PCanywhere will not work over the internet but ping works for external hosts by name or IP address, and I can telnet to outside hosts.
PCanywhere, telent, MS-networking, IE, and.... everything works on internal network.
This is REAL strange.

Was IIS on the NT box ?

Have you checked for any of the newer worms Code Red 1 and 2 etc ?? Nimda ??

Have you Checked the IE version and try to do a repair from the add/remove in the Control panel - choosing remove gives you a repair option.

Also reapply sp6a and any security patches.

I hope this helps !

SysExpert ,

No IIS running on the box, Norton AV 2001 found no viruses.
I ran a IE repair and rebooted with no change.

I'm running NT4.0sp4a.

I manualy flushed the routing table and rebuilt by hand.
After several re-bootx of both the NT and XP boxes it started working.
Got no idea what was going on.

Oh well it's all MS to me ;)
