Exchange 2007 not responding to port 25
Posted on 2013-11-02
Our sever crashed over the weekend. I was able to get everything up and running again with the exception of email.
We are running exchange 2007 sp1. I plan to do sp3 upgrade and rollups this week in prep to migrate to 2013. Before I can do that I need to get mail flowing again so the users can work before the migration. Plus I think the migration will be easier if everything is working.
So at first the transport service would not start I deleted the queue folder and restarted it and it failed again. I ran the script to reinstall the default transport agent. after that the transport services now starts without issue. I send through outlook but just can't receive. I can telnet to the server but it drops the connection right away.
I get this message when I run diags from exchange
Mail submission failed: Error message: The SMTP host was not specified..
Port 587, which is used by SMTP instance 'Client DC02', did not respond on server DC02
Port 25, which is used by SMTP instance 'Default DC02', did not respond on server DC02.
It appears that the SMTP service and SMTP instance(s) on server DC02 are started but the port did not respond. Check if there are any network errors or hung services
OWA and active sync are not working either but I think that is because I had to uninstall IIS and reinstall it. Once I get mail flow I will be working on them next.
