Jake,
Sent this in response to Kirk's Message earlier.. I accidently
sent it directly to him, rather than the list....
Minor correction, the Broadcasts are not due to WINs Server
Communication, but due to Synchronization of the Networking
Browsers (not IE or Netscape). The Networking Browsers hold
the Share Information for the Microsoft Network.
To inhibit the Netbios from causing DIALD to bring up the Link,
add the following filter rules to your DIALD:
ignore udp udp.source=udp.netbios-ns,udp.dest=udp.netbios-ns
accept udp 60 udp.dest=udp.netbios-ns
accept udp 60 udp.source=udp.netbios-ns
