Clients Disappear After Moving to a Different Group

The other day I moved a client to a different group using the web management console.  The client never showed up in the new group and no longer shows up in the group it was in either.  I even checked the database for all clients and it was not there.  The client had previously had a duplicate ID, but had just had the Repair Cloned Image tool ran on it and was showing up properly with a unique ID before I tried moving it.  It is as if the client has disappeared alltogether.  

Unfortunately, I do not have admin access to the client as another administrator is reponsible for the machine.  Short of reinstalling the client or importing the sylink file, is there anything I can have the admin try?  We are running 12.1.2015.2015.

Thanks!
