Hello, I have a strange problem which I cant seem to find an answer for. We have a fresh windows 2003 server with ISA server 2000 SP2. Everything appears to work fine, web email etc. However, when the firewall client is enabled, connections like RDP, SSH and SQL only seem to get a few Kb of data before the connection freezes. For example, if I connect to an external RDP server I get the background and half the logon box and nothing more, with SQL enterprise manager, I can connect to a SQL server and list the databases, then it freezes. If I disable the firewall client, it works perfectly. Currently everyone is SecureNAT, but I would prefer everyone to use the firewall client, if only I could resolve this problem! Any help would be most appreciated. Thanks, Ben
