I started out like you, 'it's a Samba machine, so it should be able to 
serve files', but after reading all the problems that people have had, I 
have come to the conclusion that using a DC as a fileserver is a bad idea.

Yes, if you are using a DC in a very small office (3 or 4 users), you 
might get away with using a DC as a fileserver, but in any reasonably 
sized network, I wouldn't do it.
