Exchange 2003 and Windows firewall

By courtney ·
I am using the windows 2003 built in firewall, I am allowing port 80 and 25, so OWA works fine, but on the local network I can't connect to Exchange with regular Outlook when the firewall is on. What ports do I need to have open for Exchange?

You most likely have port 135 and some other RPC required ports blocked:

See Microsoft's list of required ports:

For other programs, this is a pretty decent list:

sorry, I tried these. I don't understand. Has anyone used Exchange 2003 with the built in Windows Firewall?

maybe a better way to approach this is to make your server a multi-homed server. Using one NIC for the outside address and another NIC for the inside and apply the firewall to the outside. Then you are not opening so many ports to the outside.

that is a good ide, but this is a home test network. The server is behind a firewall with private addresses. So I feel that doing that would still be just as vunalable.

If it helps, the PC that I am using to try to connect to the exchange server is not part of the domain?

Try enabling programs in firewall

I was having the same problem. Try enabling the exchange programs listed in this article.

It says to go to the exchange program folder (e.g c:\program files\exchsrvr) and add the following programs to the firewall's exception list

? EMicrosoft Exchange MTA Stacks (Emsmta.exe)
? Microsoft Exchange Information Store (Store.exe)
? Microsoft Exchange System Attendant (Mad.exe)
? Microsoft Exchange Site Replication Service (Srsmain.exe)
