Is it a good practice to have DHCP, DNS and File sharing on the same
server? It is one of the 2 servers in a cluster.

I am new in directing Novell adminstrators and my admins tell me it is
more than fine. They say they (DHCP and DNS) should be on our most
powerfull server. My Windows' admin background tells me that file
servers should not supply services other than file sharing.

Thank you!
