Free webdav server software?

I'm looking for free webdav server software that will run in windows XP or if there isn't any then I'll even be ok with some pay software so long as it runs in XP. I do have XP professional if that matters. I know that windows server 2003 allows for this... but I really just don't want to bother with that.


There's loads of free ftp server software out there to say nothing of XP being able to do it native... but I'm not seeing anything for webdav.


I need it for calender stuff.

Apache with the DAV module?

that's a good idea... I over looked that because I have no interest in setting up a website... just a webdav link for remote calender syncing...
