  • Exchange 2010 port 25 closed

    Hello All

    This issue has been driving me crazy for 4 hours!

    My server lost power, however it came back up about 10 mins later. However Exchange has taken a 'slight' wobble in that it no longer accepts incoming mail on port 25.

    A simple telet to this port (from a LAN PC) shows:

    telnet 172.16.0.20 25
    Connecting To 172.16.0.20...Could not open connection to the host, on port 25: Connect failed

    When I was checking all the settings, I opened my Send Connector and received an error "Force Closed". I managed to remidy this by refreshing and removing the existing Send connectors and then re-adding them.

    I then removed the Receive connector, restarted the transport service and then re-added and finally restarting again. Port 25 still wont come up.

    After much faustration, I added a new Receive connector on port 26. This instantly came up and works fine. I managed to work around the issue by forwarding incoming connections on port 25 to port 26 at my firewall. By no means a fix, but a workaround for the time being.

    I also noticed when adding the new Receive connector it only populated IPv4 addresses, where before it had both IPv4 and IPv6. I dont understand this one because IPv6 is enabled on the server.

    I completely removed my AV software from the server, restarted but still the same issue.

    Does anyone have any ideas? I'm really baffled by this one!

    Cheers!

    I would recommend (if you have not already) using something to see if port 25 is open at all, and what ports are listening. I like Nmap (zenmap).

    Also, are there any other services running on this computer. Can we have some details about your OS/Firewall config (is the firewall ISA, and on the exchange server?).

    Good to be back....

      Review your event logs for the post crash startup

        Hi Guys

        Appreciate your replies!

        Forgot to mention that, I ran a port scan last night. Port 25 is showing as closed. Ran it again this morning, showing amongst others, port 26 is open. There are 2 Receive connectior configured, one on port 25.

        Regarding the server itself, its running Win Server 2008 R2. Nothing else is on the VM. I removed the AV and rebooted last night. Firewall is running on Smoothwall, again running on a VM. Hypervisor is XenServer 5.5.

        Regarding the event logs, I did initially check them. There was nothing that jumped out other that a few moans about services not starting. As soon as i saw that, I rebooted the server and everything seemed to come up as normal.

        After plowing through the event logs again, i noticed these:

        Code:

        Hopefully someone can see if the issue resides here...

          Are you sure this isn't a Windows 2008 firewall issue? . Check the Windows 2008 firewall to make sure you are allowing port 25 on the correct profile.

          You can always allow all profiles for now to rule this out as the cause.

            Hi Ste

            Cheers for your reply

            Firewall is completely turned off - and the service isnt running either.

              Hi Guys

              I appreciate the responces so far so thanks!

              Although this isnt a big issue, since exchange seems to be working ok...would it be a better idea just to restore my VM back to a clean 2008 install and re-install exchange? It may be an easier option?

              Or is this fixable?

              Cheers,

              Dave

                I am pretty sure that you need to have the Windows Firewall service running, even if you have disabled the firewall.
                I would also check that the Exchange services are running - MS Exchange Transport specifically as that is what controls the SMTP traffic.
