Hi Mark, can I ask just what you are trying to achieve ?

When you join a computer to the domain a computer object is created in 

If you examine an object for a computer you will find that there is this:

primaryGroupID: 515

The '515' is the RID for 'Domain Computers'.

What you will not find is the attribute 'memberof' pointing to 'Domain 

If you remember that a computer is a special user and that normal users 
are members of  'Domain Users' and you cannot remove a user from 'Domain 

When you remove a user from a normal group, what you actually do is to 
delete the users 'member' attribute from the groups object, this 
automatically removes the 'memberof' attribute from the users object, 
these type of links are referred to as 'backlinks'. I hope you can see 
that trying to remove a computer from Domain Computers will not work 
because the 'backlinks' do not exist.
