Group policy for USB or CD ROM Block.

Dear All,

I have applied the following group policy from domain to block USB and CD Rom access.

Computer Configuration > Policies > Administrative Tools > System > Removable Storage Access

ALL REMOVABLE STORAGE CLASS : DENY ALL ACCESS.

Now I have removed the GPO from the domain controller, but still not able to access the USB AND CDROM. Giving the following error on all domain computers. Please suggest.

THANKS.

Any Help Will be highly appreciated.
