User rights in NTFS Windows Server 2008 R2?

Question

NTFS

Good afternoon.
If in Windows Server 2008 R2 an account with administrator rights on a disk, say, K:\, removes the “users” group from access, and leaves the “administrators” group with full access rights, then my account loses the ability to access this disk. Why does this happen if I am a member of the "administrators" group?

Answer 1

Why - because UAC.
Why - because you work in an account that has administrator rights, although you should work under a simple, non-delegated account.
Why - because if you need to steer the rights - create a group, throw whoever you need there and give FULL CONTROL permission to this group. As a result, it will be possible to steer with the rights from under the usual account, and there are fewer security threats (because not admin rights), and it’s more convenient (you need the manager Vasya to steer too - just add him to the group). Well, in extreme cases, there will always be an Administrator.

Answer 2

Why is he perverted? The most standard option.

Answer 3

If the problem is local, on the server, then this is a feature of Windows 2008 - prohibition of access to the root of the disk.
If you start the console so that there is “Administrator:” on top and try to create a file, then you will succeed.
At the same time, if you share this disk and log in through the network, then access will be immediately!
