connection failed port 25

I have two w2k3 SP1 server setup with smtp for relay. Both servers are
pretty much a mirror of each other. Locally, I can telnet from one server
but not the other. When I tried to telnet locally from the servers with its
own local IP to port 25, I get connection failed to port 25. There is no
differences between the two servers except their IP.
There must be a differnece between them, did you try to portscan these
servers to see wheter the port is activated and listens. What dies
Netstat -a say ? Once we had an issue about port 25, becasue a virus scanner
was installed which blocked the port 25 to forbid open relays, perhaps this
could be a point.

Connection between Principal and Mirror servers

Hi guys, right now I am facing this scenario several times and I wonder why it can be happen. Both SQL servers are in Enterprise SP1 edition. The mirroring setup can be work fine to me. Once my principal get attacking by DDOS, then mirroring session change the status to 'DISCONNECTED'. However, after DDOS attack solved and line connection gets back on the principal server, the mirroring session still remain to the status ('DISCONNECTED'). If I restart the SQL services on principal server or mirror server, then only the mirroring session change to 'SYNCHRONIZING' status. Does anyone faced this happen before? I need some assistance on it and hope able to get any explanation or solution from you guys. Thanx and have a nice day.

Best Regards,

Hans

Are the SQL server services set to BOOT or enabled to restart on the failure.

Also chekc the SQL server error log in this case.
