You should also check the OBSCommon user in the SQL Enterprise manager. This error also pops up when the OBSCommon user's loginname is not the same as the Name. Both should be OBSCommon. If this is not the case delete the OBSCommon user and add it again with the right name and loginname. Just make sure that you also give this user the db_owner role.
Hope this helps...
