"Always read the release notes."
That's all fine and dandy when the release notes are clear about what is and what will never be. The release notes for the Exchange 2003 SLA Scorecard for MOM 2005 Reporting Services state that SQL Server 2000 with SP3 or later is required. In fact the exact text (taken from two different locations) is:
Note Administrator rights on MOM 2005, MOM Reporting Server, Microsoft Windows® 2000 Server, Windows Server™ 2003, and Microsoft SQL Server™ 2000 are also required.
Microsoft SQL Server
SQL Server 2000 (SP3 or later)
MOM Reporting Server or separate SQL Server 2000
Okay, so what did the release notes fail to mention? It failed to mention that the Exchange SLA Scorecard is hardcoded to only allow SQL 2000 SP3 or later service packs for SQL 2000. In other words, SQL 2005 is NOT supported and no work-around exist. If you want to run SQL 2005 with the Exchange SLA Scorecard, you must wait until V2 of the Scorecard, scheduled for near the end of calendar year 2006.
Of course, some of you are finding this page on a search, so I will at least put in some literals for the sake of search engines. Upon installation of the SLA scorecard, during the prerequisit check, if you have SQL 2005 installed on the SQL Reporting Server, you will get the following error and setup will not proceed: "SQL Server 2000 SP3 or later not detected." Of course it should really say, "SQL Server 2000 is required for the SLA Scorecard. Later versions of SQL Server are currently not supported."
Bummer: Another woe is discovered.
