If I can find the spare cycles, I'll try something similar and grab the 
packets.

The records do exist right after joining too, which strengthens Jerry's 
theory.

The actual strings that end up in Active Directory are found in plenty 
of SMB packets. Perhaps there's some flag we're missing somewhere that 
convinces Windows servers to update its records. Does anyone know 
whether joining a Windows NT workstation to a late Windows domain 
controller causes the records in Active Directory to be updated?
