I took over for a firm that is running two DC's with Win2012R2. We have one 2008 member server that is in the domain and one 2003 server that is in a work group, so it is not in the Domain.
When I got to Active Directory Domain and Trusts/Properties, The Domain Functional level is blank and so is the Forest Functional level is blank.
for giggles I clicked on Raise domain functional level to see if I could get more info but I get the message....
Current domain functional level: (Blank)
Exclamation point: You cannot raise the domain functional level because this domain includes Active Directory Domain Controllers that are not running the appropriate version of Windows.
How do I find out what the previous IT person set this to? I did contact him but he does not know.
