Re: [cobalt-users] DNS wit Qube2 and NT DNS???

Ok, mash me for a top-post, but there's no easy way to do this.

Chuck,

DNS and WINS are two completely different animals... don't get them
confused. Unless your environment has multiple subnets with a router or
Layer3 switch, WINS is not needed. Any queries in a single subnet will be
resolved by broadcast. Also in a single subnet, there is only one master
browser for the network neighborhood.

It sounds like you have two different DNS systems in place when you only
need one. For the moment, completely ignore the underlying OS of the DNS
servers... clients don't care about that one bit.

First, you need a single Primary DNS server. All other DNS servers should be
configured as secondary to the primary or as a forwarder. Since you want DNS
to query the WINS database to resolve DHCP-assigned host addresses, make the
primary one of your NT boxes. To my knowledge, BIND will not query WINS
(sorry if I'm wrong about this).

I have had problems with Unix boxes acting as secondary DNS hosts to a NT4
primary on a domain controller... it requires secondaries to authenticate
via NT prior to allowing zone transfers. If you must run DNS on the Qube and
it fails to communicate with a NT-based primary, simply configure BIND to
forward all requests to the NT box.

One comment about DNS on NT4... MS never got CNAME working properly, so
you'll have to ignore DNS standards and use multiple A records whenever a
CNAME should be used (sucks, doesn't it).

Now DNS in a Win2k world is completely a different story. I think MS finally
got this right. Win2k clients will register themselves with DNS... static or
DHCP. Newer versions of BIND also support this. The native Win2k design
doesn't need WINS (legacy NT clients still will).

I hope this helps.
