Windows 2000 gives error "network request not supported" With Exchange 2000 Enterprise. Can't logon locall or through RDP.
I'll start from the beginning.
I recently installed windows 2000 Advanced server, then Windows 2000 Exchange enterprise.
I moved my mailbox to the new server.
Everything was running ok for a few days, then yesterday afternoon, I stopped getting emails. When I tried to log to the server locally then through RDP, I recived the follwing error :
" Network request not supported".
Rebooting seems the resolved the problem for about 12 hours. then this moring I got the same problem.
Any help would be appriciated.
Very urgent issue, I would give more points if I could :)

I tcould possibly be the Sumantec AV for Exchange. There were two modes to choose from when I installed it, I chose the "VSAPI 2.0" or "MAPI". The first time I chose the VSAPI 2.0 - perhaps this caused the problem. I just reinstalled it with the MAPI Option. I'll monitor it for 24-48 hours.

The AV reinstall or even uninstall did not resolve the issue.
have you disbaled the Windows based firewall of the NIC ?
Have you applied all Service Packs and Roll up patches to your server ?
Are you using an ISA server to publish Exchange ?
