Can you use a traffic sniffer and capture the request packets from 
this device ? My guess is that it's put an embedded <non-printing 
something> at the front of it's ClientID (which gets stored as UID) 
and that's causing the problem.

I've seen a different but related problem with a device that padded 
out it's ClientID with nulls - causing DNS updates to fails.
