Trying to setup CNAME for all of our servers due to the
names being "generated" to actual names people could
remember. But when doing a ping against the CNAME, comes
back with Bad ip address. When using the fully qualified
name it comes backup with unknown host.

Look up the problem and found article: KB248123 that
sounds like the problem I am having, but I don't think I
have a delegated sub-zone. The DNS only has 2 zones: the
cache, and our domain. How do you tell if you have a
deledated sub-zone?

We are running NT4.0 SP6a with all the latest patches.
Working on setting up 2000 with a DNS to see if the
problem is resolved.

Thanks.

Could you give an example of one of your CNAME records and the A record you
are pointing it to?

It should be something like this:

Zone name - domain.com

www CNAME server1.domain.com
server1 A 192.168.0.1

Similar to what you show, but the cname shows up under the
A record.

Zone Name - Domain.army.mil

TSServer A 192.168.1.51
APP1 CNAME TSServer.domain.army.mil

Thanks.

Looks correct. How about if you use nslookup? Can it find the record?

Nslookup does not find record. When listing the CNAME
type, it errors out.
