RDP Licensing Error

Postby gryhound30 » Wed Apr 07, 2010 6:57 am

When I attempt to connect to some (not all) of my server 2008 R2 boxes I receive the below error. I can turn around and use RDP outside of mRemoteNG and connect without issue...any ideas?

WarningMsg
4/7/2010 8:50:47 AM
RDP Disconnected!

The remote computer disconnected the session because of an error in the licensing protocol.
Please try connecting to the remote computer again or contact your server administrator.
Error code 2056.

Thank you!

I have found out how to make it work... still don't know why it broke! This is on a Windows 7 box and it has worked fine for 6 months now. For some reason I now have to run it with elevated privileges to make connections to any machine that is running terminal services. Another person here is running it on the same version of Windows 7 and does not have to use elevated privileges to run it..... very odd behavior!

That is very strange. I can't think of why that would happen.

Well, my workaround of running it with elevated privileges fixed one issue but had issues appear in other connections. I am quite lost about this problem. My next step will be to re-image my machine and start up clean with a new file.

In registry delete this key on 32bit Systems:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing

on 64bit systems it's that one:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSLicensing
