Update for Windows 2008 R2 RDS for HD client support

Last Modified: 2015-02-01
I had a problem around 6 months ago connecting via remote desktop to a Win 2008 R2 session host using a Windows 7 HD client.

Connection kept freezing - there was not an issue when using a non-HD client.

I was able to locate an RDS update that resolved this issue - but I did not make a note of the KB number and now have the same issue on a different server.

Anybody have any idea which update it was as I can't find it - have been through all the updates installed on the server around about the time it was installed 6 months ago but cannot find anything related.

I'm assuming he means HD as in High Definition perhaps?

@devon-lad: Are you perhaps referring to the RDP 8.0 update? http://support.microsoft.com/kb/2592687

Current release of RDP is actually at 8.1: http://support.microsoft.com/kb/2923545

with RDP 8.0 update in above link Remote-FX capabilities are enhanced
I think you are referring to this update as update for HD client to improve user experience

VB ITS / Mahesh - As far as I remember I had to update both the client and the server.  Is it just a case of installing the RDP update on both the client and server?

Yep, just install on both the clients and the server. Make sure both ends have at least Service Pack 1 installed as it's a requirement.

If you're talking Remote FX though then that's a whole different ball game altogether...

RDP 8.0 client has both server and client side component
The RDP 8.0 update includes both the RDC 8.0 client and the RDP 8.0 server-side protocol components

Have just checked and all clients are on 8.1 - problem server is on 7.1.  Previously problematic server is on 8.0.

So it must have been the 8.0 update I'd previously installed on the server.

Presumably best to go with 8.1?

U can go with 8.0 1st and then you can update it to 8.1 if required because 8.1 do not has server side component

I know that
Here is information in http://support.microsoft.com/kb/2830477 with RDP 8.1 update

Co-existence with the RDP 8.0 update
This update does not include Remote Desktop Protocol 8.1 server-side components for Windows 7 virtual desktops. In other words, this update includes only the new client. Therefore, the update applies only to computers that will be used as client computers. The RDP 8.0 update includes both the RDC 8.0 client and the RDP 8.0 server-side protocol components for Windows 7 SP1 virtual desktops. If you want to have both the RDP 8.0 server-side components and the RDC 8.1 client installed on the same computer, you must first install the RDP 8.0 update and then later install this update.

Ok, just for clarity for future readers...

RDP 8.0 needs to be applied from http://support.microsoft.com/kb/2592687 on both the client and the server when using HD display on the client computer.

RDP 8.1 can further be applied but this does not include the required server components to support HD that are in the 8.0 update.  So installing 8.1 only would not fix this specific issue.

Is that right?

That only applies for Windows 7 Virtual Desktops, which the author does not use. He states in his original question that he is connecting to a 2008 R2 Remote Desktop Session Host.

The RDP 8.1 update article for Windows 7 + 2008 R2 from Microsoft states the following improvements:
Fixes connection reliability issues.
Provides better error messages for connection failures.
Resolves a time-out issue in which a connection to a virtual machine hosted in Microsoft Azure disconnects after being idle for more than 4 minutes and requires re-authentication.
Link: http://support.microsoft.com/kb/2923545

To answer your question above devon-lad yes it appears the 8.1 update does not do much to improve performance when connecting to 2008 R2 servers. If you are connecting to Server 2012 R2 machines though then there are definitely improvements there but I digress.

Can you please confirm if the RDP 8.0 update has addressed your original issue?

Yes, the 8.0 update installed onto the server fixed it - clients already had 8.1
