Hello all, Below are the network ports which needs to opened from DMZ to Exchange and Vice Versa on the firewall as per the exchange perspective as we have ISA also in place, so IS there any way that can be tested is working or Opened or Not ? Any script or some other way around. Protocol and Ports TCP 80 TCP 443 TCP 587 TCP 25 TCP 50636 TCP 110, TCP 995 TCP 143, TCP 993 TCP 389 TCP 50389

Why not use telnet? Example: telnet serverfqdn 443Martina Miskovic

while doing the above will all the ports will be validated and tested ?? Thanks

while doing the above will all the ports will be validated and tested ?? Thanks No, my example will only test port 443. To test POP, you would type telnet serverfqdn 110Martina Miskovic

understood but is there a way to test the things some another way around like sending the email or some script ...TO CHECK ALL THE CONFIGURED PORTS .. Thanks

Don't know of any script that can test all this for you, but with telnet it will only take you seconds to test it. You can of course also run tests on on the rules you have configured in ISA.Martina Miskovic

Hi Maybe this blog is helpful to you. Terence Yu TechNet Community Support

Thanks Terence i have gone through the above what you mentioned, but that is for exchange 2010 and i am looking for exchange 2007.

Hi Is this something you want to do on a regular basis or just a one time test to make sure that everything is open. Using telnet is the best solution for a one time test and you could use the connectivity verifiers in ISA for regular checking. Steve
