Remember the NT 4.0 days when it was easy to duplicate your production environment by taking a BDC off line and promoting it (on a separate LAN) to a PDC for testing... Well I have found that there really is no easy way to do this with Active Directory environments - until I stumbled upon this FREE tool. I recently used it and it worked great in replicating our 2003 AD Domain in a test lab - with no SID issues. The tool is called XSync v0.2 and can be obtained at http://www.yside.com/projects/tools.htm. I wanted to share this find with all of you out there who want to duplicate your AD environment for test purposes. Chris Wall
