Using Windows XP. I have a custom tool on it that queries a sql server db. It connects to the server db on port 1433. It goes through the ISA/TMG server to get to the SQL server. Whenever I attempt to use the tool to connect to the db, the ISA client in the tray gets a red x.
It works fine on my Windows 7 machines.
On the ISA server, it records an entry:
Denied Connection ISASERVER 06/12/2011 13:48:18
Status: The action cannot be performed because the session is not authenticated.
It seems that the client disables itself, so the ISA server sees it as an unauthenticated session.
Tried a few different ISA client versions.
