Is this by design? if so, is there a way to prevent this.
Basically, once the first user signs onto the server and the drive auto maps, every subsequence user signing on to the server will have accesses to that drive and hence all the user’s personal files.
If the drive item’s option is set to ‘Mount on boot’ it will be accessible to all user of the system. It’s because the drive item is mounted using system account of Terminal Server. We need to use system account to mount the drive item because the user is not logged on.
If the drive you mentioned is not a drive item with above option. We need to inspect the issue further.
