Windows 7: Connect to WebDAV

I want to map a webDAV directory (on an apache server) as a network drive,
but I can not connect it from windows 7. Crappy 3rd party apps work allright
(so the server itself is up and running), but I'd rather use it as a drive.



I tried several methods found on forums, but none of them worked. I wonder
if in the past few months a solid workaround was found...
