Hello All,

We have a jump server of windows 2012r2 on which terminal server is installed and when am trying to mstsc that server it is not working however with mstsc /admin switch it is working fine.

Below are the steps i have taken but no luck.

  1. Checked remote desktop services and remote desktop licensing service it was in running state, not only this all the services are in runing state but tried restarting this both services.
  2. Checked remote desktop licensing and diagnoser evrything looks good with userbased cal which is having 150 license out of which 80 is issued and 70 is available.
  3. Terminal server group in AD contain this computer object added yes it was validated
  4. builtin object in AD called terminal server licensing group is also having this computer object added.
  5. Atlast i did rebooted the server and it started working fine.

But again same issue came yesterday last week some other application server who is having terminal server installed was also facing same issue but after reboot it fixed the issue

I believe there is concrete solution for the same and am missing exact cause behind it. Please help and advise the next course of action to get it be fixed.

    Hi,
    For mstsc and mstsc/admin, If you have RDS roles installed on the remote sever, mstsc /admin will allow users to remotely administer the server. So firstly I consider that you could launch gpedit.msc, navigate to Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> User Rights Assignment -> Allow log on through Remote Desktop Services. Check if it had the group Administrators.
    Have you met some error when we use mstsx to RDP? Does Event log record some information?
    Meanwhile, you prompted after reboot it fixed the issue. Did you do something before this happened, such as install updates, change the group policy?
    Hope this helps and please help to accept as Answer if the response is useful.
    Best Regards,
    Carl

    @Azhar Shaikh Hi,
    I'm sorry to see your message when I just came back from vacation.
    Thank you for your information.
    According to your description, I suggest that we could check for update, if any security update could be found, please install them to check.
    Then check Microsoft-Windows-TerminalServices-RDPClient/Operational event log.
    Hope this helps and please help to accept as Answer if the response is useful.
    Best Regards,
    Carl
