I have MOSS 2007 with SP2. When KB979445 was installed on the QA SharePoint servers I starting getting audit errors: SafeControl load exception:Microsoft.SharePoint.Portal, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c Exception: Could not load type 'Microsoft.SharePoint.Administration.ISPGroupMigrator' from assembly 'Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c'. As far as I know there is not a ISPGroupMigrator in the MOSS 2007 namespace only SP 2010 or is it also in the MOSS 2007 SP2 and the security patch overwrote it? Should I re-install SP2?

Hi, If you make sure you have installed SP2 successfully, I think maybe there are some failures during this security update installation. Also, to install this security update, please refer to: http://support.microsoft.com/kb/979445 http://technet.microsoft.com/en-us/library/cc263467(office.12).aspx#section4-a http://support.microsoft.com/kb/903771 Hope it is helpful!Seven
