Guest Neal Posted August 31, 2007 Posted August 31, 2007 Hi All, I'm a trying to set up Exchange Server 2003, but every time my only client machine tries to connect using Outlook XP it hangs and then displays "The connection to the Microsoft Exchange Server is Unavailable". If I turn off the Windows Firewall on the server it connects fine. So I'm figuring I need to open some more ports on the firewall, but I don't no which ones to open. Here's the current list C:\WINDOWS\system32\dllhost.exe C:\WINDOWS\system32\lsass.exe C:\WINDOWS\system32\ntfrs.exe C:\WINDOWS\system32\scshost.exe C:\Program Files\Exchsrvr\bin\emsmta.exe File and Printer Sharing C:\Program Files\Exchsrvr\bin\mad.exe Port 110 TCP Port 123 UDP Port 135 TCP Port 137 TCP Port 143 TCP Port 25 TCP Port 25 UDP Port 3268 TCP Port 3269 TCP Port 389 TCP Port 389 UDP Port 42424 TCP Port 464 TCP Port 464 UDP Port 53 TCP Port 53 UDP Port 636 TCP Port 67 UDP Port 80 TCP Port 8098 TCP Port 8099 TCP Port 88 TCP Port 88 UDP Remote Desktop C:\Program Files\Exchsrvr\bin\srsmain.exe C:\Program Files\Exchsrvr\bin\store.exe Many Thanks Neal

Do you have a good firewall appliance between your network & the internet? Don't rely on Windows for that.
