I have the several workgroup PCs that must connect to a database hosted on SQL 2000 on a Win2k server on a domain. The database is configured for mixed mode. If I try to set up an ODBC System dsn using SQL Authentication, I get a Server does not exist or access denied error. I can connect to another SQL2000 database on a different Win2k server ok. I can successfully set up the System DSN using SQL Authentication if the PC is added to the domain. As soon as I try to access it when the PC is returned to workgroup configuration, I can't connect. so it looks like an issue with this particular server. NT auth does not work for obvious reasons. Any clues anyone?
