Black desktop on domain admin login

 I had just installed server 2019 and could login locally with an account. But after connecting to our local domain, I would get a black desktop when I logged in with the admin domain account.

This would happen on both on the server and via remote desktop connection (RDC).

After a lot of stuffing around with google search details only relating to black screen on RDC, I eventual found a link to this page:

https://community.spiceworks.com/topic/2274333-server-2019-black-screen-on-rdp-with-domain-admin-account#entry-9086513

There were a lot of suggestions, which were good, but the one that worked for me was a solution from the user mimo1313:

Hello All,

I had the same problem with server 2019. Change following setting in local GPO:

Computer Configuration->Windows Settings->Security Settings->Local Policies->Security Options

Enable "User Account Control: Admin Approval Mode for the Built-in Administrator account" which is set to "Not Defined"

After that do a gpupdate /force and try to login as domain administrator again

This solution did work for me!   

Once you have logged in to the problem account and black desktop do the following:

  1. Using the keys ctrl-alt-delete (or ctrl-alt-end for RDC) start up task manager.
  2. When it opens, click on File and then click "Run new task"

  3. When the "create new task" small window opens, type in:
    gpedit.msc
    also tick the box below that allows admin privileges.


  4. Once the Group Policy Editor (GPE) opens, navigate through the options as mentioned above:
    "Computer Configuration->Windows Settings->Security Settings->Local Policies->Security Options."
    (see the image to what you need to find.)


  5. In the options in the "Security Options" topic find:
    "User Account Control: Admin Approval Mode for the Built-in Administrator account" which is set to "Not Defined", and Enable it". Click "OK" to save it.


  6. Close the GP Editor and open task manager again. This time we need to create a new task and type in "CMD" and tick the admin privileges again.


  7. Once the Command window opens, Type in the follow command:
    gpupdate /force
    This will force the new changes on to your local machine for your domain admin account.

  8. Either log off or restart and log back in again, with your domain admin account.
You should be all good to go. Thanks to mimo1313 for sorting out a solution. :)
