Have just installed comodo firewall. Have not crawled up the learning curve yet, but one thing I noticed was that there is no way to disable netbios for a given network. Have I missed something? I looked in the help file, but I did not see any entries for netbios or file and printer sharing. I set up a rule to block TCP local ports 137 and 138, but perhaps there is a built in option I missed. Any comments would be appreciated.
