As well as disabling the Browser server, "unbinding" File and Print and MS
Client on your external adapter, if you haven't already should help a bit.

This is NetBIOS traffic. ISA is blocking Computer Browser service broadcasts
and name resolution requests from going outside, a VERY good thing.
BTW, %systemroot%/system32/drivers/etc/services is a nice place to check for
port descriptions for anything below 10000.

Anyone know what would be using this port?
The system that's spitting out thousands of requests is a Lotus Notes SMTP Mail
Gateway. It is configured as a published web server thru ISA...but ISA is
blocking all its attempts to connect to various systems using UDP 137. Its
certainly not mail...as all the servers functions are acting just fine.
