Terminal server error

[mrbios]

I'm getting this error in the event log:

The RDP protocol component X.224 detected an error in the protocol stream

 

Only way to get the server working and serving up remote desktop connnections (be it from a dumb client or a regular desktop RDP connection) is to restart the server, google seems to give me loads of info on windows 2000 problems but nothing pointing to this problem on a server 2008R2 server, any one come across this and able to advise?

Is it an upgraded server? Or a fresh install? That error usually indicates something wrong with license/certificates.

 

How to resolve the issue

It's a fresh install. With regards to the certificates the "RD Session host configuration" certificate setting is "Auto generated" should i apply a domain certificate to this (this server is purely for the purpose of dumb terminals to connect to internally) certificates confuse the ******* off me!
