I have still the problem with the error "Internal error in communication channel" under LMS 3.2 with three Win2k3 servers.
In 90% of all tries to configure credentials under common services I get that error.
I tried the same change of credentials directly on the server, accidental with Firefox. And it worked!
After that I tried the next credentials on my workstation with firefox, and it worked, too!
Firefox is version 3.5.3.
IExplorer is version 6.0.2900.2180 SP2.
I installed IE v7.0.5730.13, it worked, too!
Any ideas what I can do to use IExplorer because the IE v6 is our standard...
