Hi
For connecting Biztalk Server 2004 installed on windows 2003 server to Sql Server 2000 installed on Windows 2003 in another forest domain, It is necessary to Turn Rpc Security off .Is it also necessary to establish cross forest trust between the forests?

Thanks
Swapnil

It does not sound like you have exactly the same issue that I did, but this article led to security settings that got MSDTC to work for me. http://support.microsoft.com/?kbid=873160
