Hello, I have laptop with ISA Firewall Client installed. I move between 2 locations, 1 is using ISA Server so no problems. The other location is still running MS Proxy server 2.0 but I am having problems to receive e-mail through the MS Proxy server with the ISA Firewall client. So the question is, can ISA Firewall client work with MS-Proxy 2.0? Funny thing is when there is one MS-Proxy client connected with the MS Proxy server 2.0 I am able to connect to the pop3 mailserver to receive e-mail? Thanks in advance.
