Don't try this at home

For work-related reasons, I installed a copy of vanilla ZoneAlarm on my dev box at work (running Win2k3 Advanced Server). I went ahead through the "This is not a supported operating system" warning, and everything went OK, until it came time to restart to activate the firewall.

90 minutes later, I had the login prompt, and 90 minutes later yet, I was logged in. So I uninstalled and rebooted. It was still logging out after being left overnight, so I just pulled the plug.

When it restarted, all was OK, but it was a pretty hairy experience, all in all.
