I have my DNS server set up. It allows me to log in to the domain. It also seems to be forwarding request correctly using forwards but when I do a nslookup it always tells me Can't find server name for address 10.1.10.150 Non existent domain**** default server not available
Default server Unknown
Address 10.1.10.150

Any Ideas why this is coming up????

Everything seems to be working except sending emails using exchange and outlook???

"This error occurs when there is no PTR record for the name server's IP address. When Nslookup.exe starts, it does a reverse lookup to get the name of the default server. If no PTR data exists, this error message is returned. To correct make sure that a reverse lookup zone exists and contains PTR records for the name servers."

When I did this I got a error
Warning the assosiated Pointer PTR record can not be created probably because the refrenced Reverse lookup zone can not be found.

However I do have a reverse loook up zone and in them is
0.in-addr.arpa
127 " "
255 " "

Any thoughts

Is your Domain Controller the DNS server for your domain?

yes my domain controller is the DNS server as well...

First of all, the message from NSLOOKUP that it can't find the server name is not an error and is not limiting the functionality of NSLOOKUP or anything else in any way, shape, or form.

If you do still want to clean it up just for good order however, then you need to create a new Reverse Lookup zone on your DC/DNS server for your network 10.1.10.0 (not sure how many bit mask you're using). Once you've created the reverse lookup zone, do an IPCONFIG /REGISTERDNS on your DC/DNS server and check the newly created reverse lookup zone to be sure that the PTR was automatically created for your server IP. Once this is confirmed, perform an NSLOOKUP and the message should be replaced with the server name.

In my DNS manager it has revers lookup info listed. But when I look at my computer manager under DNS the reverse lookup has no information under it. Why is that?
