Thanks for the response Al

We've had a Windows 2003 Server and a Snap appliance which has worked fine. Recently added a Server 2008 R2 which we installed as a separate domain (didn't know what else to do) and now suspect that Server 2003 and Server 2008 can be made to work together better but don;t really know how.
