I'm not suggesting that this could simply be used without thought or effort. The serious implication (for those who don't realise what a problem protocol NetBIOS is already) is that if one is allowing netbios traffic through a firewall, intending to allow only authentication perhaps, apart from the obvious file and print access possibilities, the range of exploits is actually infinite, based on what commands can be executed using psexec.
I agree that NetBIOS is a horrid beast to be avoided. But can't people who need to just stick NetBIOS on top of TCP/IP? Then you can use existing rules to filter that. Drop any other kind of packets (like IPX, NetBEUI) and if a luser complains, then you know that they haven't got their machine set up properly.
