Hi, Im trying to create a trust between two of my servers and i want the "Forest" option however it is not available. Does anybody have any clues as to why that may be? I have made sure that all the domains and forest levels are 2008, so thats defintely not the issue. I have 7 MS Server 2008 Enterprise, 1 Ubuntu Router, and 2 XP PC's. Configuration: I have made all of the servers domain controllers, 4 of them have dns, one of them is read only. Domains = perupizza.com are.perupizza.com lim.perupizza.com worldpizza.com Thanks Heaps to whoever can help.

two of those appear to be child domains in the same forest. perupizza.com - root domain are.perupizza.com - child domain lim.perupizza.com - child domain No forest trust possible there. Now worldpizza.com appears to be its own forest. Have you reviewed the forest trust check list? http://technet.microsoft.com/en-us/...

Hi, Yeah im trying to create a 'forest' trust between perupizza.com and worldpizza.com. I've already checked over that check list. I'm still not sure what im doing wrong. Any suggestions??

can you do a nslookup between the dc in one forest and the dc in another and visa versa

Well before i changed some settings to try to get this to work i could do nslookup normally. Now it gives me the answer but it says its a "non authoritative answer". Its probably something simple im missing, i just havent done this stuff in a while.

This means that your DNS server queried an external DNS server in an effort to resolve the IP address associated with the requested domain. From the checklist If there is no shared root DNS server and the root DNS servers for each forest DNS namespace are running a member of the Windows Server 2003 family, configure DNS conditional forwarders in each DNS namespace to route queries for names in the other namespace.
