Exchange 2007 SP2 Upgrade error

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

Go to adsiedit.msc

Go to the location mentioned in the error message:-
Properties of Cn=Microsoft Exchange security groups and look for an attribute "Otherwellknownobjects"
Delete the entry under this.

I have done the otherwellknowobject check in asdi edit. That value is not set
Try running PrepareAD on exchange 2007. This will set the defualt permissions for security groups.

I Ran setup /prepareAD from an elevated command prompt logged in as  enterprise administrator account
And BTW I appreciate everyones help at least I am looking in the right areas

If this makes any differenc this is an exchange 2007 server that I put into a new domain then used the ADMT tool / PS to migrate all of the exchange user accounts with mailbox's and SIDs on to the new domain / exchange server
It is in production currently
Have you checked the otherwellknown objects on cn=Exchange servers?
If this is also empty then, You will have to use LDP utility to find the guid value and remove it.

Ok Problem resolved the otherwellknow attribute on CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=sms,DC=edu  had a semicolonfor the value. It would not let me change it at first and took about 5 or 6 tries before I was able to edit it.
Used LDP.exe to select the well know naming context of configuration and then looked at the properties of cn= Microsoft exchange and the other wellknownattribute was set incorrectly there. Thans for everyones assistance
