I also have (past) experience with a network running MS/NetBIOS cruft through routers with forwarding of directed broadcasts DISABLED. It worked fine. If there is some corner case I've missed that requires forwarding of directed broadcast packets, it would be useful for that specific case to be enumerated _in detail, in public_. Ran rja@home.net We ran MS Windows over routed network in seven localities without any type of broadcast enabled. All what is needed for user transparent operation is to setup WINS.
