Just did a fresh install of Sage 100 2021 Premium.  When printing any report, getting error 15 SY_REPORTCOMMON.PVC 1877.  O/S Error 28000 [Microsoft][SQL Server Native Client 11.0] Login failed for user "MAS_User".  Verified the password is correct for MAS_User. 

Checked the event viewer on the SQL server, the log says "Login failed for user MAS_User. Reason: Failed to open the explicitly specified database TEMPDB.  SQL admin checked to make sure MAS_User has rights to TEMPDB.

Any advise as to what to check.

Thanks,
Nelson
