Minifiltering network I/O

NTFSD
1

Is there anything special I need to do in order to filter network
I/O? Debug output from my InstanceSetup shows that the filter has tried
to attack to \Device\LanmanRedirector but no I/O goes through the
CreatePreOp.

Yes, if you attach to \Device\LanmanRedirector you will see I/O in the
Create pre-op. If not, you’re doing something wrong.
