"Windows Networking" will masquerade just fine, at least the session protocol,
because this is simply done with a TCP connection. The "Windows Networking" name
service will never let you see everything in the Network Neighborhood over IP Masq.
because it relies on broadcast UDP which IP Masq. does not handle (and should not
ever handle, IMO). If you have the machine's host name in DNS or in your hosts file
you should be able to get to the machine by going to the 'Run...' and type
\\hostname. It *may* work if you don't have the host name in DNS or locally if you're
using a WINS server. If you're not using WINS it won't work because this uses
broadcast. Of course you can always enter the host/ip into your windows box's hosts
file. NOTE WELL: even if you enter the host/ip into your hosts file you still will
not see the machine in the Network Neighborhood. Yes, the difficulty with the Network
Neighborhood over anything othen than a small LAN bums many people out. However, the
mechanism which makes this evil thing work is fragile and flaky at best and those
responsible for it should be beaten. If you're interested in finer details of this
mechanism I'd be happy to discuss them with you offline.
