Adding Active Directory tools to your workstation
Grab this update from the Microsoft website, the one above I use is for 64 bit OS’s (x64), download 32 bit if you’re running 32bit OS.

After it’s been successfully installed go to the Start Menu > Control Panel and select “Programs”;
“Turn Windows Features on or off” under “Programs and Features” |

Click “OK” to make the changes.
In order to make finding these under the Start Menu a little easier right-click the Start Button and select “Properties”;

Taskbar and Start Menu Properties |

Under the Start Menu you will now see an “Administrative Tools” option, under this you’ll see the new AD Tools;
Use Active directory Users and Computers to check if computers are in the “Unmanaged” OU and move them if needed to Desktop/Laptop OU’s.
Common signs a machine is in an unmanaged OU:
-
build process doesn’t complete.
-
When elevating rights, it doesn’t accept your username/password.
-
Prompts for username, password, domain when making an SCCM RT connection
-
Iprint printers don’t add after adding them via interface
*Note: there are some machines purposely left in unamanged OU due to being a NAS server or a specific purpose, or a vendor managed machine, please leave these in unmanaged.
