The connection to the Microsoft Exchange Server is Unavailable

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
