In my organisation Windows Server 2012 is installed & domain is also configured. Even the group policy is also applied. there is gp for block usb also. Two days back I had removed an OU from the block usb policy. But till now the users in that OU can't access usb flash drives , cd & dvd drives. whenever they try to open it it shows access denied. Its more than 48 hours since i removed that particular OU from Block usb policy. If I do RSOP.msc it doesn't show block usb policy.
Please help me why it is not getting applied.
