I have implemented a group policy in 2012 Domain Controller to block the USB Removal device. The Group policy is successfully deployed and the USB device was block. But when i removed the group policy it has been found that it has disable the USB Storage driver. In device manager it is showing exclamation mark. Then i have to uninstall it and then again i have to install the driver manually on the machine. Then it works. Its becomes manual process.
We have done Gpupdate on both Domain Controller and on the client Machine. I have run the rsop also.
