Here are some simple steps to determine the Functional Level of your Windows Domain/Forest:

1. Open up the Active Directory Domains and Trusts MMC found in your Administrative Tools folder. (Also found in the Control Panel or in the Start Menu).
2. To check the domain functional level, right click on the current domain and select Properties, this will show you the current Domain and Forest Functional Level.
