The connection to the Microsoft Exchange Server is Unavailable


Recommended Posts

Posted

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

Hmmm - what's the reason you're using the Windows Firewall on your server?

Do you have a good firewall appliance between your network & the internet?

Don't rely on Windows for that.

 

So I'm figuring I need to open some more ports on the

You might have more luck posting in microsoft.public.exchange.admin. Mention

whether your Exchange server is a member server or DC.
