From what I recall from the course so many moons ago there is no such thing as a PDC/BDC anymore... shite! I will dig that tidbit up first.

You're thinking about Active Directory I recon and how it's meant to replace PDC/BDC, it was added in Win2k Server. I'm unsure of the pro's and con's of AD but I suspect that a lot of them don't apply to a small network like yours. What I can be certain of, however, is that PDC/BDC IS still present in Win2kSvr.
