I would like to run an IRC server for users of my LAN, and my best option would be to do so on a Windows XP box. Is there a decent Windows/Cygwin IRC server that you have used and would recommend? If so, any configuration pointers would also be greatly appreciated.

Changes to environment variables should take effect immediately, if you make the change via the main Properties dialog for the computer in question (go to My Computer | Properties | Advanced | Environment Variables). After the changes are saved, Explorer broadcasts a WM_SETTINGCHANGE message to all windows to inform them of the change. Any programs spawned via Explorer after this should get the updated environment, although already-running programs will not, unless they handle the setting change message.
I'm not able to tell from your problem description what specific problem you're having with this. Can you tell us more about the specific scenario that isn't working?

I've played around with the Windows build of Unreal IRCd. It's annoying to configure if you've never configured a Unixy IRC server before, but there's always the website to help you out, and on the plus side you get portable knowledge (all the concepts as well as most config files can be ported straight to a Unix machine.)
