I just reinstalled my work computer to Windows 10 Pro, created a local account, connected to our VPN, joined our domain and logged in with my domain account, no problems so far.

Since the local account is automatically in Admin group, I'd like to add my domain account there as well so that I can install work software and run things as admin without need to provide an admin password every time I do so.

But when I try to add the domain account to admins, it doesn't allow me to add someone from other domain.

When I go to my domain account and try it there, it finds my domain account, but tells me that I don't have persmission to do that. And if I run control panel as admin with my local account, them I'm back where I started.

Why can't I add a domain account to Admin group from my local account? I did that in Win 7, Win 8 and Win 8.1 with no problems, before. Do I have to ask our domain admins to log on to my computer and add me in or is there a way to do it?

  • Where are you attempting to do this? In "Computer Management | Local Users and Groups"? – Daniel K Aug 9 '15 at 10:32
  • @DanielK Yes. I also tried Management Console, but I guess it's the same. – Ondrej Janacek Aug 9 '15 at 10:40

To add an account as a member of the administrators group you need to be a local administrator already and you need to have rights to read the active directory information. A normal user can do this so what you want to do should be possible:

  1. log on as local admin
  2. connect on the VPN
  3. open Start | Computer Management | Local Users and Groups (or run lusrmgr.msc)
  4. double-click on the 'Administrators' group
  5. click the 'Add...' button

At this point, because you are on the VPN and the machine is a member of the domain, you should be able to click on the 'Locations...' button and select the domain as the location of the user list. At some point an authentication dialogue should pop up and you will need to enter your normal domain credentials.

  • Ah, I have to be connected to VPN, I didn't realize that before, but now it makes sense. Thank you very much. – Ondrej Janacek Aug 9 '15 at 11:56

All the above answers are correct. If you want your Domain User to be a local Admin on the Windows 10 Pro PC, you have to make sure the Domain\User is added to the Admin Group. However, even if you do that, you will still get pop ups saying you don't have permission. This happens because once you join a Domain in Windows 10 Pro it adds Domain\Users to the User Role. You have to remove the Domain\Users from the Users Group. Restart PC and then your Domain User will have local Admin permissions. Cheers.


by adding a computer to a domain automatically the "domain admins" group is member of local administrators.

For this reason it is usually not required to add specific accounts if they are already member of the domain admins group.

  • Manually authentifying by entering the domain admin account and password was exactly what OP wanted to avoid. – Patrick R. Feb 13 '17 at 17:26
