Disable EOA (Ease of Access) on the logon screen - Windows 2008

A client connecting to my Windows Terminal Server (2008 R2) somehow managed to activate the EOA button.

After reading a million forums - I finally decided to do the following:

Took ownership on the file: c:\windows\system32\utilman.exe 

Renaming the file to utilman999.exe

Now the user don't have access to that file and it CAN'T be called up.

How annoying............

Terminal Server 2008 - Corrupt TS License Database

The terminal server license database is hold in

c:\windows\system32\lserver\

I fixed my corrupt database by stopping the licensing server, renaming lserver to lserver_old - doing a restart
Starting the terminal server licensing service - it will fail.
Then rename the lserver_old back to lserver and starting the licensing server again.
