Tybio: I can't access the site myself at the moment, but I remember vaguely what you're talking about.
Some things to check would be that the service useraccount is configured correctly, as well as making sure the netsh commands have been run allowing port 9321-9325 to be opened by anyone rather than just the Administrator. Finally, make sure these ports are open in your firewall (even on the loopback adapter if applicable).
If all else fails, try renaming your Settings.xml file and rebooting the computer - as a "faulty" settings file could still cause problems in 08116.
You could also dig through the Eventlogs and see what pops up. There should be an exception and stacktrace logged somewhere pinpointing what the service was up to when it died.
spplutchok: It's all good. I probably overreacted a bit myself reading your "initial" post. As for lightning striking - I've been joking about that to my wife the past couple weeks (as we've had some really weird weather) saying we no longer require insurance against lightning nor surge-protectors as it never strikes twice in any one place :) That being said I'm currently in the process of sourcing some RJ11/45 protection which I can place everywhere external cabling is entering the building. Of course it won't take a direct hit, but should offer some protection against nearby hits.
everyone: Thanks for your supporting emails/PMs.
