It’s a 29.6mb MSP file, that is basically a manual windows update file. It doesn’t arf take some time to apply.
Talking to Richard, he said that the Rollup will actually update the exchange install package and cause it to perform a “repair” and applies the new files.
That way if you do need to “repair” the exchange installation it will have this rollup included!
Update Rollup 1 for Exchange 2007 includes the following fixes:
932487 – The Microsoft Exchange Information Store service stops unexpectedly when the Exchange Server 2007-based server replicates the Public folder
929756 – The DoSnapshotSet method may stop responding in the Exchange store, and a backup application stops responding on an Exchange 2007 server
The KB for the fix can be found here: http://support.microsoft.com/?kbid=930809
I cracked the MSP open MSIX (http://blogs.msdn.com/heaths/archive/2006/04/07/571138.aspx) and found 959 files with file versions ranging from 8.0.693.0 to 8.0.708.3. So it must have more than the two fixes listed above
What is a concern is that the rollup doesn’t actually change the version shown in the Exchange Management Console. With or without the patch is says Version 8.0 (Build 685.24). Would be nice is this was updated to you know what servers have patch But I suppose I understand in a way. You can see if the patch has been applied by going to Add/Remove programs and Checking the “Show Updates” box. This will then show:
-Microsoft Exchange Server 2007
— Update Rollup 1 for Exchange Server 2007 (KB930809)
Hope this help
