Ok, its not too complicated, basically in windows 2000 there is no PDC and 
BDC, only Domain Contollers all of which are equal.  Now that said, there 
are a few master services such as the globabl catalog server that are 
created on the first DC in your domain, but you can move them around, they 
aren't tied to one particular machine.  In essence however all Domain 
Controllers in win2k are equal, however to maintain backwards compatibility 
with NT4.0 (which requires a PDC be present) win2k has a PDC emulator that 
pretends to be the PDC for NT machines.  In this way you can use win2k and 
NT4.0 in what is called a "Mixed" environment, some of the features of win2k 
are not available except in "Native" mode but you can't use native mode 
unless you have no machines except for win2k (and I think XP is also ok) 
this includes NT, Linux, Mac, etc.  The PDC Emulator will be on the first 
machine that you created in the domain, though you can move it to another 
one if you need to for some reason.  Hope that helps.
