I've had a problem with my Administrative Shares disappearing on the domain controllers in my Win2000 network. C$, D$ and Admin$ all evaporate after a reboot. I can recreate them but they go away at the next reboot. Haven't been able to find anything helpful in Technet. Looked at my Winnt.adm file and everything seems to be in place there. Any Ideas?
