I have heard conflicting statements regarding whether you should run DNS on a Windows 2000 Domain Controller with Active Directory. I have a number of clients who are currently running NT 4.0 and have a BDC at each remote location on their WAN. This BDC is also a DNS server and is a secondary copy of the primary DNS server running on the PDC. These clients don't have the $$ to buy servers for different services so they were thinking of updating to Win2K in place with their existing hardware. Any thoughts?

I find it is good to put DNS on a DC. AD does alot of lookups and writes to DNS, so putting them on the same box is fine.

Remember that if your domain is gonna span the whole organisation, then its best that you do put dns on the dc. If you re gonna be running active directory, then you can run an active directory integerated zone which will span the whole organisation(if you put a win2k DC at each site) . admin will be easier as well as reducing DNS resolve queries over the organisation.

Thanks, that's what I thought too. It's always good to get confirmation.
