Hi there. Can you tell us the error you\'re getting when you try to scan?
The \"File and Printer Sharing\" exception is basically ports 135-139, so you shouldn\'t need to open those manually. And Remote Management shouldn\'t need to be enabled to scan with Newt.
Unfortunately, this isn\'t so much a scanning issue concerning Newt Pro specifically. It\'s a general remote administration issue. Basically, you need to be able to get to the ADMIN$ share of a remote PC, as in \"\\\\RemotePC\\ADMIN$\" from Windows Explorer or IE.
Using firewall settings that don\'t alert, are you able to get to the ADMIN$ share? And with those settings, are you able to ping the machines by name?
