1) Pull the plug on the system. It's likely being used to send spam, kiddie
porn, or to attack another network.

2) Make a full backup of the system.

3) Try using fport or a similar tool to track down the application or
executable that has the port open.

4) Try to figure out how it got there, and how it can be removed. Document
this.

5) Reinstall the OS, and rebuild the system. Restore data from your last
known good backup.

6) Patch and test your system.

7) Buy a firewall!!!

8) Put 'er back on the 'net.

Hi!, I understand that is the SMTP service of those
computers (the ones out of my domain), the thing is that I
donīt have any Mail Application running, and my SMTP
Service is off(I mean I turn it off), I also use the
netstat command and my server is still sending the packets.
Thanks.
