I have a set up with two connection servers (A and B), a Security server and a farm. Connection server A handles all the internal connections while connection server B handles all the external connections through the security server. Suddenly, no one can connect from outside. If I connect to connetion server B from insider our network, directly (not going through the security server) it works fine. If I connect to the security server from inside or outside, it will connect to the connection server, and show me the applications that I have access to, but when I try to launch any of them, it gets as far as saying "A connection has been established and the application is loading" but then times out or says "The connection to the remote computer ended" I have looked through several of the windows event logs on all three servers Security, connection B and the farm, but cannot find any reason the applications will no load if I am going through the security server. It worked last week and I don't know what has changed.
Any help that can even point me in the right direction would be greatly appreciated.
Bob
