User: foo\srv_moss_ssp_app

Computer: MOSS

Description: The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {BA126AD1-2166-11D1-B1D0-00805FC1270E} to the user foo\srv_moss_ssp_app SID (S-1-5-21-1929346206-854414880-475923621-21603). This security permission can be modified using the Component Services administrative tool.

Solution

Well, I don’t know how, but the default SharePoint groups WSS_ADMIN_WPG and WSS_WPG were removed from the Windows\TEMP directory. This causes the cascading failures shown above. To resolve the problem just add the groups back to the folder. Give WSS_ADMIN_WPG Full Control. Give WS_WPG Read & Execute, List and Read rights.
