From the “Administrative Tools” menu, select “Active Directory Domains and Trusts“.
1:Right-click the root domain, then select “Properties“.
2:Under the “General” tab, the “Domain functional level” and “Forest functional level” is displayed on the screen.
You can also use steps 2 and 3 from within the Active Directory Users and Computers snap-in to see the same screen.

For   “Active Directory Domains and Trusts“ on the domain controller or a computer running the Administrative tools run the following at the command prompt.

For Active Directory Users and Computers,
 Click Start, and then click Run.
    In the Open box, type dsa.msc, and then click OK.
