Windows Server 2003 (Small Business Server) and Windows Server 2003 - Terminal Server; both servers have all current Microsoft patches.
All users can run the company Business System (Byte) from any LAN connected PC.
When connected to the SBS server via RDP (remote desktop connection) using the Terminal Server, only users with Domain Admins group membership can run the program. We added this group membership to one of the normal users, and the software worked fine, just like it does wen connected to the server via their office computer, on the LAN.
If we remove the Domain Admins group membership, the business system will not start. We have confirmed that the user has "allow user to log in remotely via terminal server" enabled, and have followed numerous KBs and found everything set.
Users (without Domain Admins membership) are able to connect via RDP, and do everything else. Is there another setting that we have missed?
