I have a situation where I need to integrate an existing AD running on
server 2008 R2 with DSFW (OES2). These are 2 branch offices that are
being merged together.

Both of these systems are using the same domain name (abc.com) with the
same NetBios name (abc).

I suspect that I will run into issues if I create a Trust between these
2 systems

I'd appreciate any ideas on how to integrate these 2 environments.
