Remote Desktop Fails and server logs schannel error

Connecting to a remote desktop server fails and the server logs and error with the source: Schannel; Event ID 36888.  Schannel errors are usually down to problems with SSL and certificates.  This case is no different.  Simply run mmc.exe and go to “file” then “add/remove snap-ins” and select “certificates” and choose “computer account”

Next navigate to remote desktop > Certificates and highlight the certificate with the computer name listed in the “issued to” and “issued by” field and delete it.

certificates

 

Once the certificate is deleted simply disable then re-enable remote desktop services and restart the remote desktop service service.  This should regenerate the certificate and you should now be able to connect to your remote desktop server again.

  1. I tried the solution and it works just for one connection. After that i have to delete the certificate again and it works just once.

    Do you have any idea?

  2. The failure aplied after installing KB3121212. After restoring the system without this security update it works fine.

    Now the same issue with KB3126587 and KB3126593.

    Deinstalling the updates won’t help. Need to restore the system and don’t install the updates.

    What a shit!
