Microsoft, Windows, Server 2003 SP3 32 Bit Enterprise, AVG Corp Anti-Virus Server - No access to Network resources..

Ok I have this issue on 3 of 7 servers... and I am stumped...

all servers have Windows Server 2003 SP2 Enterprise,

Server 1 is a Terminal Server
Server 2 is the AVG Corp Virus Admin Server
Server 3 is an SQL2000 Server

none of the 3 can access the Internet (and Server 2 needs it to get the AVG Virus Definitions) and none of them can access Network Resources..

none of the computers in the company can connect to Server 2 to get Virus Definition updates.


HOWEVER:

I can remote desktop to all of them, our SQL Client Software (Dynamics Nav 5.0) can access the SQL server without issue.

But I cannot from IE access any websites, or internal web-pages (such as webmail from my Exchange Server, or my WSUS (Windows Server Update Services ) server.

I cannot see any other computers from the My Network Places --> Entire Network Window.

I can connect to shared drives by using \\computer name\share name from "My Computer" but not from IE

Any Ideas?  I'm stumped..

from a command line do a route print - my first guess would be some kind of network issue
my 2nd guess would be firewall-related oddness

if that was the case then all the computers in the rack on the same switch would be experiencing the same issues, don't you think?

I can get to some resources and not others, I can remote into the servers no problem..

I have tried using another switch, as well..  

I am more inclined to believe this is a software problem, not a hardware problem at this point..

too add to this

Server 2 is also a DNS server, and watching my firewall it is broadcasting on UDP 53 just find..

so it can connect to the internet, just not on port 80

no it appears I am receiving invalid permissions error messages on these servers..

the Domain Admin account can not install, uninstall any software, access the Root of the "C" drive, access network drives etc..

the local Administrator account is having the same issue..

our AVG virus software says no viruses found, I don't see anything out of the ordinary running on the task manager..

I am attempting a complete reinstallation of the Terminal Server...  But I can't and prefer not to do that to my SQL server

ok, this appears to have been an issue with the latest update from AVG..

after removing AVG, corp server and the AVG anti-virus software, manually clearing the registry and reinstalling both from scratch, everything is back to normal
