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
