I have a full MS BI stack (SSRS, SSAS, SSIS, SQL Server - all 2008, Developer edition) running on Windows XP Pro (work requires this OS).
If a user is in the administrators group local to the machine, they can access Reporting Services from a second machine without receiving an authentication challenge (i.e. NTLM appears to be passing the credentials correctly). If the user is not in the administrators group on the
SSRS box, they get the NT challenge dialog. A colleague and I have tried everything, we could possibly think of as well as googling ad nauseum.
I have to resolve this issue so that we can use the XP SSRS box for testing with remote users.
