Cause

This problem may occur because of the following scenario. One published network uses the Requests appear to come from the ISA Server computer option as the server publishing rule. Other published networks do not use this option. Secondary outgoing traffic from the networks arrives at the published server from the same IP address and port. Therefore, ISA Server 2004 may disconnect all the networks when you close your connection to one of the networks.

Resolution

To resolve this problem, use one of the following methods:
  • Change the network relationship to Network Address Translation (NAT).
  • Change the server publishing rule so that the traffic appears to come from the clients.

    Note For networks where the traffic appears to come from the server, use one IP address in the server publishing. For other networks, use a different IP address for each network.
