The network has 7 server 2003 Enterprise boxes on it. The IP set is 10.0.xx.xx. Matthew runs ISA and Surf Control. Last Wednesday, everything worked fine. This morning, Surf Control is down (down meaning it is not blocking any traffic based on the rules we've written) and we cannot RDP from Matthew to any other server on the network. The error at RDP attempt is:
Because of a protocol error detected at the client (code 0x1104), this session will be disconnected.
We were on the phone with Surf Control and they say it's an ISA issue. When we go to Services and turn off the Microsoft Firewall, everything works fine so we feel sure it's an ISA issue as well. However, so far as the three network admins are concerned, the network has been static. No IMAC's within the last two weeks.
Network logs are silent. Googleing the above error message reveals only a FEW similar problems and none relating to my problem.
Anyone have any thoughts on this?
