I think it is referring to your Active Directory which must be in Native Mode. Below are the steps to convert:

Start the Microsoft Management Console (MMC) Active Directory Domains and Trusts snap-in.
Right-click the domain you want to convert to native mode, and select Properties.
Select the General tab.
Click Change Mode, as the Screen shows.
Click Yes in the confirmation dialog box.
Click Apply to return to the main dialog box.
A success message will display.
Click OK.
Reboot the machine.
