So Don't Do That. [tm]

MACHINE.SID holds the identity of the machine, as far as NT domains are 
concerned.  If you delete/recreate it, other machines who are supposed
to recognize you won't.  That means that if you were a domain member,
you no longer are.  If you were a domain controller, the domain members 
may or may not continue to trust you.

Are you a domain controller or just a domain member?  If you're a
domain member, you will need to rejoin the domain, the same way you did 
the first time.  If you are a domain controller, your clients may need
to rejoin the domain (I don't know), the same way *they* did the first
