Subject:Embedded RDP connections fail

Hi,
Could you take a look at the topic about NLA here?

Thank you David, I tried with SingleSignOn on and off but it fails anyway.

Could you post the error message you get?

David,
I am receiving the same type error. If it is the same thing then it never gets to the point of asking for the credentials which would have been fixed by the SSO check box. What is happening in my particular case and possibly Victor's as well is that a session setup to use Tabbed mode fails with a message of "The remote computer disconnected the session due to an error in the licensing protocol. Please contact you system administrator." And while typing this I fixed my own issue though you may have a more elegant solution. If you set the permissions of the shortcut to "Run as Administrator" you will be prompted for permission to run as Administrator (depending on your UAC settings) but after that the sessions will open in tabbed mode. Not sure if this is a one time setting I will test further and reply back again :) One sysadmin/support guy to another :)

Ok just tested and you do have to leave the Run as Administrator option checked, I was thinking that after the initial run that the registry access that was needed would no longer be needed (I just recently had to update my CAL and I know that after updating a RDP CAL there are registry strings that get updated and that requires Admin level privileges) but unchecking the Run as Administrator option brough the error back. Also as a note the Run as Administrator option needs to be set for ALL shortcuts that you may want to run RDM from (Start Menu, Desktop, Startup Folder, etc.) it will not propagate on its own.

Hello David, Attached is the error I get.
I also tried to run shortcut as Admin (thaks for the help) but in my case it was not enough. I still get the same error.
One note from my side may help on resolution: The only way to run on tabbed mode is enabling "Open in console". Unfortunately, I haven’t admin rights on target machines.

Could you take a look at this thread?

That was the key!! Thanks a lot David.
And congratulations for your really good, and above all, quick support
