How to remove the Mouse Keys PopUP in Windows Server 2003 running Terminal Services?

Dear Sir,

I have three Windows 2003 TS 64 Bit Entreprise Edition, running Windows application. These servers are joined to a domain.
My users keep activating the Mouse keys options within their Windows sessions (Ctrl+Shift+Numlock). I want to know how to completely remove these options from the servers.
Does anyone has any idea how to stop this PopUp window appear on the screen???
Any GPO or option?

Any Help Please?

Thank you in advance,

I think you need to disable the mouse keys via the accessibility options in the control panel

I hope this helps !

Thank you,

Through Group Policy, change the flag number of the MouseKey in registry \ accessiblity to 58 instead of 62.
