Problem with connecting to NT 4 PDC from W2k DC

After I changed IP address of my W2k server, all Trust with other domain based on NT 4 drver were broken. When I tried to establish trust again "[domain] cannot be contacted" error appear.

When I check if W2k server can resolve DC i saw following error:

C:\>nltest /dclist:[nt4 domain name]
Domain '[nt4 domain name]' is not an NT 5 domain.  (Using NetServerEnum).
I_NetGetDCList failed: Status = 6118 0x17e6 ERROR_NO_BROWSER_SERVERS_FOUND

I suggest that you run both dcdiag /v and netdiag /v on all your WIN2000 Servers. Have you done this? if not then You can also download these two utilities as individual files. The Support Tools are located in two places: on the WIN2000 Server CD in the Support | Tools folder and on the WIN2000 Service Pack CD in the Support | Tools folder.
Alternatively, you can go to http://www.microsoft.com/downloads and simply search for 'dcdiag' and
'netdiag' and find them.

I would also check to make sure that the TCP/IP information is correct. Is this machine showing up in DNS? How about after the reboot?

also u could try this too.
force this to demote
DCPROMO /FORCEREMOVAL ( so that it is no longer a DC ) and then running dcpromo on it again ( so that it is a DC again )?
