client access license could not be upgraded,

Hello,

After an update of the licenties on one of my terminal servers i always get the following error ;


"The remote was disconnected because the local computer's client access license could not be upgraded or renewed."

This is only when i open the RDP session in Tabbed mode.

When opening via MSTSC there is no error.
The Reg key is there.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing

is this a know error ? (i can't find anything about this on the forum)

Thanks
Kim
