We have an app that can use mssql2k or 2k8. We've been using 2k but I decided to try 2k8 to compare. I installed in on our win2k3 server alongside mssql2k. In the ODBC applet on the server, I was able to set up access to 2k8, and it passes the test at the end successfully, whether I tell it to use Windows Authentication or an sql login. The latter is how the app always accessed mssql2k. The app works fine from the server, but when I try it on a workstation (winxpsp3), I get a window titled, "Microsoft SQL Server Login" that says:

Connection failed:
SQLState: '01000'
SQL Server Error: 53
[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()).
Connection failed:
SQLState: '08001'
SQL Server ERror: 17
[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.

Then I get the ODBC login dialog, which I can't get to login correctly (I just keep getting the same error above), even copying and pasting a password after resetting it on the server, and whether "trusted" is checked or not. "Options" is disabled.

The server was straight SERVERNAME for mssql2k, but for mssql2k8 it's called SERVERNAME\mssql2008. That works on the server, why not on the workstation? (Which I'm logged in as the same person on, BTW.)
