In previous post , I mentioned on how to disable drive mapping on Server 2003 via GPO. In this post, I will show on how to disable drive mapping on server 2008. Description : Disabling drive mapping on Server 2008 How To Do :  Access to GPMC , edit the intended GPO. Browse to Computer Configuration > Policies > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Device and Resource Redirection Click at ' Do not allow drive redirection  '. That is our target setting Right click at it, and press Edit  Choose Enabled , press Apply and OK .  You can double confirm the setting by checking at ICA-TCP and RDP-TCP Properties. They are now checked, and  grayed out. And this is the explanation by Microsoft on the GPO setting.
