Adding AD group to local admin on W2k8


Ive got a problem when adding an AD group to the local admin group of a server, Im able to add the group to other servers but not this one. They are all in the same domain/ou etc but for some reason this one server wont allow me to add it. When I enter in the AD group it states it cannot find the group?

Ive had this before but cannot remember for the life of me what I did, it was real easy step but just cant remember?

Any ideas

on the server in question run this at your command line
net localgroup administrators /add domain\account

**of course substituting the domainname\nameofgroup**
