Ok, stupid question from an AD newbie. I have 1 domain with 5 sites. Each
site has a DC. Should the DCs be set to use themselves as DNS servers in
TCP/IP, or should they all be pointing to the root server?
Think of DNS as being totally seperate from AD. Any DNS server can
hold information about any Domain, regardless of its location in the
forest. All a Windows 2000 AD Domain needs is for it to be able to
locate a suitable DNS (one that supports SRV records). The DNS servers
could all be on the moon provided AD and clients can find them. (Of
course lookups might take a while!)
OK, rant over.
I assume that each DC runs AD integrated? In which case machines on
the local subnet should point to the local DNS server which in your
case *happens* to be the local DC. The local DNS server should use
itself as DNS (otherwise it will look up over the network - not good).
Each DNS server should be set to forward requests, ideally, to an
external DNS through the Internet gateway, such as your ISP's DNS
servers. They could however forward to the network DNS closest to the
Internet gateway. That one alone would forward to the external DNS
servers.
Cheers,
Cliff
