Question : How to stop sharing the D drive?

If I select the D drive properties and want to stop sharing the drive but...
a message appears as if I would have clicked on the C drive.

"This share was created for administrator purposes only. The share will reappear when the Server service is stopped and restarted or the computer is rebooted."

But I don't want to share the D drive. That isn't a system drive.
How can I stop sharing the D drive for good?

If they are admins then they can get around this  - do there is little point in what you are attempting. If you want to prevent access to your files create an encrypted folder and store you files in that (don't forget to export the encryption key for safety - its best to keep a copy of the key to recover your encrypted documents in an emergency).

If you encrypt files then only yourself, anyone else you decide to add, and the Data Recovery Agent, if its a domain, can access your files even if they have the necessary NTFS and share permissions
