We have a Remoting app built in VB.Net, .Net Framework 1.1, using Windows
Forms and tcp channels ("tcp://localhost:8085"). The Server program runs as
a Windows Service and the Client program runs on networked workstations (100
Base T). The data resides in a shared directory on the server
("\\[servername]\data"). Our forms update on all workstations as users add
or modify data. However, if there is a firewall we have to disable it in
order for this autoupdating to work. (We are testing with ISA Proxy Client).
Is there a way to get the autoupdating to work with the firewall on?

I am having the same issue. Everything was working fine -- we could auto
update our C# applications on the users workstations. Then a couple of
weeks ago, we update our antivirus software, Vexira, and we can no longer
auto update our .net applications. To update an existing .net application
we have to disable the antivirus. I have been searching for a solution and
found none. Any help, ideas, would be much appreciated. Thanks.

open the particular ports on firewall or use http/binary (port 80) solution
instead of tcp/ip...and for some cases you would have to use http/soap
which is the slowest communication architecture but if you're inside your
LAN there will be no problem... but for WAN prefer to use web services
technology... if that doesnt do your work than write your own or buy 3rd-
party channels for getting through the firewalls/nat by using several
tricks... especially the projects about p2p networks could be delicious to
review!
