Curtis, I had run across the same prob. a week ago. And I used keepalive 0
on both the ends (if using promiscuous on one end, use prom-peer-default and
set keepalive 0) to resolve it.
I think it should work for you.
I verified it at the following url...
http://www.cisco.com/warp/public/697/dlswdodisdn.html
ps. this url doesnt refer to netbios keepalive filter, but you will need it
in your case since you are using NETbios stations (aka windoze pc's)
