It sort of sounds like something else has port 22 as Tom has suggested.  But, if you
are able to start it after the system is up that would mean whatever had the port has
released it.  Kind of odd.

Some questions....

What type of network card?  Wired/Wireless?

Is the IP address setup as static, or is the system getting it via DHCP?

When you start the service....what are the resulting lines in log/secure?
