When I do an NSlookup from a command line on a windows XP Pro or another 2003 server I get the following response
C:\Documents and Settings\ificuser>nslookup 10.1.1.05
*** Can't find server name for address 10.1.1.88: Non-existent domain
*** Default servers are not available
*** UnKnown can't find 10.1.1.05: Non-existent domain
The domain controller is working and active directory is working, everything seems to be working ok. I can see server shares and everything else, so I am a little confused on what is going on here.
