I have this wierd issue with my DNS. If I assign a static ip to my machines (laptop or desktop) I am unable to resolve local servers, PCs, devices etc. via DNS even using NSLOOKUP (e.g nslookup server01) I get the error

*** can't find server01: Server failed

but if I allow the machines to take IP addresses via DHCP everything works fine.

Any ideas where to look? I even tried manually puting the INTERNAL DNS IP from PDC.

Edit ~ I am also able to access the internet so the DNS is working for external items.

Are the DNS servers assigned by DHCP options different than the one you set statically? – MDMarra Dec 2 '09 at 2:26
I presume Windows Server DNS and DHCP .. otherwise please update the question. – tomjedrz Dec 2 '09 at 2:26
@MarkM - They are the same internal DNS servers. – Saif Khan Dec 2 '09 at 2:31

Your DHCP server is probably also handing out your domain's DNS suffix. Can you do nslookup (or server01.mycompany.local not sure of your dns setup)?

If you do an ipconfig /all you'll see an entry labeled "Primary DNS Suffix" while you have a DHCP address to see what it should be set to. Alternately you can go to your TCP/IP properties and click "advanced" then go to the DNS tab, it will show you what your DNS suffixes should be if you do that while you have an IP via DHCP, then you can replicate those setting manually when you give yourself a static IP.
