Issue
Can not open LonMaker database
Error window pops up saying "Invalid parameters - LNS error #44"
When you click on OK it pops up another window asking you to either attach or detach the network. Once this is done, it comes up with an NSS assigned error.
Environment
Windows 2003 server, with SP1 installed.
Cause
If you have Windows Terminal Server installed (used for remote desktop connections to the server) then LonMaker does not work.
Resolution
Fully uninstall Windows Terminal Server (you don't need the CD for this operation) and reboot. You can not just turn the service off in Windows, this has no effect at all.
