If you want to "enforce" compliance, get M$ on board.  Otherwise it
ain't gonna fly.

I had good luck with $PREVIOUS_JOB with getting the company to
implement a "policy" of what host names should look like and then, when
a user tried to register a host via the helpdesk, the HelpDesk
personnel 'enforced' the naming standard.  (We also ran into several
places where non-compliance "broke things".  (And no, I don't remember
what they were...)

I personally, whenever I saw a non-compliant hostname, would contact
the user and tell them that their hostname, formatted thus-and-so,
could cause problems and "Why don't you let me fix the name for you?"
990 times out of a 1,000, I got a "Go ahead.  Let me know when you're
finished."  ($COMPANY's host table had some 48,000-50,000 names in it
any one time...  There were MANY chances to excel there.)
