nslookup 1

[johng75]

we have an internal DNS server, it is manually set and my default DNS server but when i do an NSLOOKUP is says

***cant find server name for address 192.168.xxx.xx: non-existant domain
server: ISP DNS Server
address: xxx.xxx.xxx.xxx

and all my lookups go through my ISP's dns server instead of mine.....any ideas why?

when logged on to the server itself and do the nslookups the work fine, both internal and external lookups.....

I am assuming that you are just typing 'NSLOOKUP' without any parameters, correct? Do you have your ISPs DNS Address listed as your secondary DNS server? If so, remove it so that you are only pointing to your internal DNS. What happens when you do an NSLOOKUP now?

***cant find server name for address 192.168.xxx.xxx: non-existant domain
***default servers are not available
default server: unknown
address: 192.168.xxx.xx

but it allows me to do lookups???
example

>espn.com
server: unknown
address: 192.168.xxx.xx

non-authoritative answer:
name: espn.com
address: 199.181.132.250

Sorry, I thought I posted the question earlier...
Are you getting any errors in the event logs. Something like Event ID:708 - DNS running in cache mode?

The reason for that is that you don't have a ReverseLookup zone configured for your subnet. When you use nslookup, it looks for a PTR record that matches the IP of the DNS server so that it can tell you what the server's name is. If you don't have one, it gives you an error about not being able to find the server name, but it still allows you to query it, since it has the IP address. It's just an annoyance, and easily remedied.
