Hi Steve,
 
So, you have a PPTP client behind the ISA Server firewall and browsing
is slow while connected to the remote network? Try configuring the
browser as a Web Proxy client and all will be well. Unless you're
running Lynx, I'm sure your browser supports the config.
 
HTH,
Tom

        ISA On Win2K/SP4, firewall/SNAT client running Win2K/SP4 behind
it.  Client can browse the web, do FTP, whatever.  Web proxy client
stuff is off, IE uses the firewall client to browse the web.  DNS is
running on the ISA box as a forwarder only, all LAN systems use the ISA
for DNS.

        I enabled (Microsoft) VPN on the client to connect to a
Microsoft VPN server out on the internet.  As soon as it activates,
browsing and etc is slow on the client and the ISA server cannot browse
the web.  ISA server Event Log also shows this:

        " 
        Server publishing rule [DNS Query Server] that maps 10.10.2.1:53
UDP to 129.42.16.99:53 for protocol [DNS Query Server] failed because
the port on the external interface is being used by another application.
The Firewall service failed to bind socket for the server on the
firewall since another process is using the same port. Check for any
other process using the same port and terminate if necessary. 

        " 

        " 
        Server publishing rule [DNS Zone Transfer] that maps

by another application.  The Firewall service failed to bind socket for
the server on the firewall since another process is using the same port.

necessary. 

        " 



        1.  How do I get my VPN client to play nice and not take over
the ISA?. 

        2.  How can an internal client take over the firewall service,
when it had a lock on that port initially? 



        Thanks.
