clients unable to resolve internal DNS address's that point to another location


I have internal users who are unable to resolve internal IP address's which are A records that point them to systems that run at our remote site. I am unable to ping or tracert to the internal address's. However if I change the A record entry and route over the internet it is okay and they can connect. When I attempt to do a nslookup on my client I am receiving this, which I have never seen before.

        primary name server = localhost
        responsible mail addr = nobody.inval
        serial  = 1
        refresh = 600 (10 mins)
        retry   = 1200 (20 mins)
        expire  = 604800 (7 days)
        default TTL = 10800 (3 hours)
Default Server:  UnKnown

Thank you

Your nslookup syntax is wrong. If you want the A record, just do 'nslookup hostname.domain.tld'. If you want the reverse lookup, do 'nslookup'.

You tried to do a lookup on a non-existant zone.
For the ping and tracert, please take a look at the firewalls between the two sites and make sure there is a tunnel and route set up.
