A method of disabling the network sharing feature in explorer...

Hi All,

I am enquiring about a method of preventing (all) users from sharing file
systems through explorer or any other means in a Windows NT, 2000 or XP
environment.

i.e. is there an ioctl or a flag that will turn off this feature, or an
error you return on an ioctl to a file system?

Currently the file system that we are developing does not yet support
opportunistic locking, so we want to be able to disable the sharing.

Regards,

Ian

Hi,
Opportunistic locking is not mandtory, all you need to implement is return
STATUS_OPLOCK_NOT_GRANTED to FSCTL that requests oplock. As far as I know
there is no way to prevent creating a share for a volume.
