Question

The bottom line is that there is a GPo, there is a chain of stores, they are subject to policy, the policy states that drive C is hidden. Only drive D is open, but 1 store closed for a while, and later opened, it had the drive letter E at first, then I changed to D for correctness. But access to it was closed, writes that it is blocked by policy, although everything is ok in other stores, help with solving this problem
