Recently, I needed a to determine if an Active Directory Domain was in native or mixed mode. After some research I came across a way to do this for Windows 2000 and 2003 domains. This script combines those two methods and can be used to determine the mode for Windows 2000 and 2003 domains. The one command line argument it expects is for the Windows 2000 domain mode determination. It works best if this script is executed from a machine that is member of the domain that is being queried.

This sample script uses the named command line arguments to pass the domain information to script. This is the domain that will be checked for type, native or mixed mode.

Pay close attention to the lines wrapping in this sample, the script does not have any multi-line statements.

I hope this post helped out. If it didn't, I am always looking for new scripts to add so submit a request for your question or need and I will see if I can answer it.
