Strange DNS Response..
I have domain name that look like (toto.tata.com) but is not a registered DNS for the world. I am forwarding to an external Company DNS when we need to resolve Internet addresses. Now since two weeks now, I am experiencing strange resolution responses from the dns. For example if I try to ping an existing PC on my network let say "PC01" then I receive a TTL=57 with an address: 18.104.22.168 , witch is as you can see an Internet IP. Now this is not happening on all my network machine (chance ?) but if try to query or ping let say anything but something existing on my network then I also get an answer from this IP..
My environment: Win2000 DNS Server AD Integrated.
any Idea about what is happening to me here?
Thanx in advance for your helps ..

Whenever you ping a hostname with no periods in it, then the system configured dns suffix is appended to the hostname when attempting to resolve the domain. You may have multiple dns suffix's configured in which case each one will be tried until it gets an IP address.
You can see this happening more clearly with this command:
nslookup -debug PC01
If you still don't know what is going on, then I want to see the results for the above commands.
