Hi, We are trying to promote our MS to become an RMS. We are following the http://technet.microsoft.com/en-us/library/cc540401.aspx (How to Promote a Management Server to a Root Management Server Role in Operations Manager 2007) document. Once we reach the promotion step : ManagementServerConfigTool.exe PromoteRMS We receive the following error: 2011-02-09T16:02:57.0209396-05:00 Error: Warning: Unable to trace instance space due to exception 'The type initializer for 'Microsoft.MOMv3.Setup.MOMv3ManagedCAs' threw an exception.' 2011-02-09T16:03:12.2241619-05:00 Always: Could not load file or assembly 'Microsoft.Mom.Common, Version=6.0.4900.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. 2011-02-09T16:03:12.2241619-05:00 Debug: We are running SCOM 2007 R2 CU3 on a Windows 2008 R2 box. Thanks George

Hi, Firstly, please ensure the “ManagementServerConfigTool.exe” is the one which comes with the SCOM 2007 R2 installation media. May I know if the “ManagementServerConfigTool.exe” you ran was located in C:\Program Files\System Center Operations Manager 2007? If not, please copy this file to that location and run the command again with an elevated command prompt. Meanwhile, I would like to share the following with you for your reference: How to Promote a Management Server to a Root Management Server Role in Operations Manager 2007 http://technet.microsoft.com/en-us/library/cc540401.aspx Hope this helps.
