In my DNS search order on my Win2k Server, I have my PDC and BDC, which are also my DNS servers, with WinNT4 OS.  When I do an Nslookup from my Win2k server, here's the error I get:

***Can't find server name for address xxx.xxx.xxx.xxx:  Non-existent Domain.

It says this twice, once for each of my DNS servers...  What am I doing wrong??

If you go into the NSLOOKUP program and it immediately gives you an error message something along the lines of:


*** Can't find Server name for address...
Non-existent domain
*** Default servers are not available
Default Server: Unknown
You are experiencing a common problem caused by an improperly configured reverse arpa (in-addr.arpa) zone.

When the NSLOOKUP program starts it goes to the TCP/IP configuration for the system on which it is running. From the configuration it determines the IP address of the DNS server that the system is configured to use. The NSLOOKUP does a reverse lookup using the IP address of the DNS server and tries to determine the name of the server.

If the reverse arpa zone for that IP address is not set up correctly, then NSLOOKUP cannot determine the name associated with that IP address, and it displays the error message given above.

To fix this problem you need to properly configure the reverse arpa zone for the IP address of the DNS server, and make sure that the reverse arpa is properly delegated to the server.

jshob is correct about configuring the reverse lookup zone. Don't forget to create the appropriate PTR records for your DNS servers - or you'll get this error even if the RLZ is configured correctly in every other aspect.

Thanks.  I know now what the problem is, however I still do not know HOW to configure it properly.  The article lost me about half-way through...

Thanks again!

I know this topic is stale, but I didn't understand exactly what to do in depth after I read the answer.

Anyway,

In win2k you must go to your administrative tools and DNS.

Once there, goto Reverse Lookup Zones, create one (using your subnet when asked)

and then all you have to do is place the IP addresses of your DNS servers and the name you want them to reverse resolve as.

Do this by right-clicking and choosing create pointer (the word for which PTR stands)


Thanks for the help you guys.
I'm just now learning all of this stuff... (I'm 19 so give me a break)
