If you are like me and are using Win 10 1511 and have installed RSAT you will notice the tab’s inside ADUC are missing.
This is due to a bug with RSAT version v1.2 published 12/10/2016.
Upgrade to a higher build of Win 10 e.g 1607 Anniversary edition. You may be able to try and find an earlier version of RSAT, this may work also.
If you find a link to the older version please let me know and I’ll post it here.
