When using net view and the connection has the shares properly mapped
(Windows XP firewall 'OFF') it returns the shares on the server as expected.
When the Windows firewall is 'ON' the shares didn't map and net view
complains of network path not found. In any case it doesn't see the named
server with net view when Windows firewall is 'ON'. That in spite of the
fact that the rasdial command executed OK and gives the confirmation of the
connection on bottom right of XP Pro desktop. Pinging the FQDN of the server
replies but pinging just the servername gets no reply. I checked the links
you provided but there weren't any specific references to what I am seeing.
For whatever reason it seems as though the problem is related to an anomaly
between Windows firewall and the BEFSX41. Bear in mind an otherwise
identical configuration works on the other site with a BEFSR41. At my next
opportunity I am going to turn off the firewall on the BEFSX41 at the remote
site and check the result. I can't get over there for a couple of days. I'll
post back when I have some results.
Thanks, John K.
