Trusted Domains DNS issue

Villain

Ok so I have two windows 2003 DC Servers each with their own forest, I want to create a trust between them but I can't get them to resolve the netbios names.

i.e. server1 is dc for dc01
server2 is dc for dc02

I can't ping server1.dc01.ad from server2 so the trust can't be setup because dc01 can't see dc02.

Now I have tried many different enrty's in LMhosts and I get server1 to ping dc02.ad and I get it to ping server2 but I can't get it to ping server2.dc02.ad which is what the DC trys to connect to when it trys to create the trust.

I thought LMHOSTS on server1 should contain:
192.168.1.10 server2 #PRE #DOM:dc02.ad # DC02 group domain

Anyone got an ideas how I can resolve this DNS issue??

Mods if you think this should be in Windows forum please move, thanks.

move this to net / comms for a better response ?

Can we move it to Windows to see if anyone can help?

Assuming you have a PHYSICAL link between both networks. Also assuming they are on different IP ranges.. then you simply need to give them 2 IP addresses... Unless there is a reason you do not want to do that?

The two networks are connected through the same router and they have IP addresses assigned, I can ping the IP addresses no problem its the DNS that I'm having the issue with you can't use ip addresses for creating the trusts.

AD relies on DNS, not Netbios. Besides mapping the names to IPs there are a number of service records the DC's need to create in your DNS structure to facilitate AD functions. Make one of your servers a DNS server, set it's DNS Server under IP config as itself, set it as the DNS on the other server also. If need be stop and restart the Netlogon services on each server to force them to register their service records. Ping by name and once that's working have a go at the trust.
