Hi,

This is a bit off-topic, but this has always been my favorite place to get
answers to tricky questions like this.

We had an arrangement with our backend ISP where they provide us with
secondary DNS service.  We switched backend ISPs, and so we made new
arrangements for a secondary DNS.  The problem is that in testing this new
arrangement, we're getting a strange error message.

Our own address pool is 66.224.41.x, and our new secondary DNS server is
204.250.116.119.  I believe they set this up as a secondary IP on that
server (it also holds either .17 or .18 as its primary IP) so that they
would have the option of later splitting the IPs (running one DNS server on
.18 and one on .19).  We created an A record in our zone that points to this
new secondary DNS server.  So the A record is for dns2.bcwebhost.net
pointing to 204.250.116.119.

Now for the error message:
When I run nslookup against the new secondary DNS server, I get the right IP
back, but I also get an error message.  Here is an example:

[within a command prompt on a Win2k machine]
**************************************************************
C:\WINNT\system32>nslookup www.bcwebhost.net 204.250.116.19
*** Can't find server name for address 204.250.116.19: Non-existent domain
Server:  UnKnown
Address:  204.250.116.19

Name:    www.bcwebhost.net
Address:  66.224.41.51


C:\WINNT\system32>
**************************************************************

That was referencing the secondary DNS server by IP.  When I reference it by
name, I get this result:
**************************************************************
C:\WINNT\system32>nslookup www.bcwebhost.net dns2.bcwebhost.net
*** Can't find server address for 'dns2.bcwebhost.net':
Server:  bcnetserv.bednarzconsulting.com
Address:  10.0.0.1

Name:    www.bcwebhost.net
Address:  66.224.41.51


C:\WINNT\system32>
**************************************************************

This was performed inside our network, so it apparently got the right IP by
going to our primary DNS internal server (which forwarded the request to the
real primary DNS server).

My questions:

1. In the first scenario, what does it mean by "Can't find server name for
address 204.250.116.19: Non-existent domain"?
2. In the second scenario, why did we get "Can't find server address for
'dns2.bcwebhost.net'"?

Thanks,

Ben
