I'm developing an application that uses XML Web services deployed on IIS on Windows Server 2003. The client application is a Windows Forms application, and it accesses the web service fine until I make the server a domain controller, then it gives all kind of file not found errors when trying to access the service. If I don't make the server a domain controller, I find I can't access the SQL Server 2000 (MSDE) database from another client on the network. What do I need to do to make the web service accessible when I set up the server as a domain controller?
