RDP issue rdpcorekmts.dll Application error Event id 1000, Windows Server 2008 R2

One of the Win2k8R2 running client access Exchange as upgraded to SP1. Did the same for other servers. Only one came up with issue. Checked the version of rdpcorekmts.dll version on the server with issue
with issue: version 6.1.7600.16952
without issue with sp1 version: 6.1.7601.17514

Followed the solution from here:

Just a quick note the file is update by Windows Update KB2667402 not KB2621440. Please see for more details.
1) Connect remotely to affected server using the Computer Management Console
2) Stop the Remote Desktop Services
3) Take Ownership of file C:\Windows\System32\rdpcorekmts.dll and assign full NTFS permissions to your account
4) Rename file to rdpcorekmts.old
5) Copy file rdpcorekmts.dll from a non-patched server. I used another one of our domain controllers just to be safe.
6) Start the Remote Desktop Services
7) Test RDP login to server
