Serial number blocked by firewall? How do I solve this?

When I use the server administration settings I get an error message saying the serial number could not be used because it's blocked by the firewall.



I know I'm using the right serial number.


Totally stumped.


Any ideas?


Version. 10.6.8

Mac mini

Is this a new Mac Mini Server system with a new serial number?


Is this Mac running as a guest in a virtualized configuration?


Has anytbody been working in the shell via Terminal.app in this system?


Does the Mac OS X Server firewall have the port open for port 626 under Firewall > Settings > Advanced? (It's usually listed as rule 1.)


As a potential brute-force work-around: (re)download the 10.6.8 combo update kit, and apply it, and see if that clears this.


Better: if you just acquired this Mac Mini Server system (new), ring up Apple support and ask for assistance here.
