License Manager Access Denied

All of a sudden on production machines I'm getting the following when trying to launch license manager.

I checked that my account is part of the local administrators group and the AELicMgr group.

I verified trusted connection using PowerShell command Test-ComputerSecureChannel and it returned true.

The IT group claims there are no issues and they didn't change anything.

What is causing this issue?

  • Could you try to use the modern browsers, such as Chrome or Edge?

  • Still getting the same message in both Edge and Chrome.

  • Hi,

    I don't know if it is possible, but could you try remove from and then add the computer to the domain again?

    I have seen similar issues when a machine has been cloned or renamed and the domain controller has issues with the specific machine SID.

    At least its something to try if you are running out of options. When I have done this I have changed back to workgroup, and then immediately switched back to the domain, without reboot. (If you reboot before joining again you need to log in using a local account).
    This requires that you have an account that allows you to add the computer to the domain.

  • Also, I note that your error message indicates that it is the trust with the Primary domain (the one you joined) and an additional domain that fails.

    This could be when you have a domain that your computer join, let say prod.local, and the user account that you authenticate with, is on a different domain, ie office.local, then there is a trust between these domains for this to work.

    You log in with youruser@office.local on a computer that has a FQDN of mymachine@prod.local 

    This could add to the complexity of your troubleshooting, but could also explain why you get True on your Test-ComputerSecureChannel powershell.
    The computer has no issues with the domain that its joined to, its the user that you authenticate that is on a different domain using "External Trust" (Between domains in different forests) or "Forest Trust" (Between two Active Directory forests).
