http://blogs.technet.com/b/jhoward/archive/2005/08/03/408572.aspxSo hot off the heals of getting MOM 2005 installed with SQL 2004 SP4 , I find out that SP1 for MOM is now available. Now they tell me... quoting from the SP1 homepage (link at bottom) " Broader OS and database support, including &lt;snip&gt; and SQL 2000en-GBTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.technet.com/b/jhoward/archive/2005/08/03/408572.aspx#408587Wed, 03 Aug 2005 17:58:05 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:408587danielvsHowdy John, The MOM SP1 fixes the bug of installing MOM 2005 database on a SQL 2000 SP4 database. There was an issue with MOM 2005 not being able to see that SQL 2000 SP4 was newer as SP3 and therefore canceling the installation. In my post there's a link to a fellow MOM addict with a detailed description of all the fixes en issues solved with MOM 2005 SP1. He also posted a thread to the MOM newsgroup as he had an issue installing MOM 2005 SP1. It seems to be that MOM 2005 SP1 needs the latest Windows Installer version that ships with Windows Server 2003 SP1. There is also a seperate download for the correct Windows Installer version. <br> <br>I hope this helps!
