Create a block rule in NetMon.
One for: IN; source- the IP’s of those PC’s; destination- file server.
The other for: OUT; source- file server; destination- IP’s of the pc’s.
With these two rules, all comunications to and from those PC’s are blocked. Create the rule in the beggining/ top, or move it to the top.

I think ;D

thanks,i’ll try tomorrow
