Trying to install EX2007 SP2 in preparation for 2010 migration, giving this error:
The well-known object entry with GUID 6c01d2a7-f083-4503-8132-789eeb127b84 on the otherWellKnownObjects attribute on the container object CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=sms,DC=edu refers to a non-USG CN=Exchange Servers,OU=Microsoft Exchange Security Groups,DC=sms,DC=edu. Please either delete the well-known object entry or promote the target object to a universal security group.
The object it is talking about is already a USG, and I am reluctant to delete the group. I have used ASDI edit to look at the properties and made sure they did not have any invalid characters
