[Zope] Problems with Ms-webfolders, iis, and pcgi

[Jay, Dylan]

I am trying to gain access to Zope via webdav with the MS-webfolder client.
This seems to work fine when I connect to Zope directly. However I also run
zope behind iis using pcgi. When I do this I get an error saying there was a
problem (but not details of what that problem was. If I use DAV explorer
then I can see it behind IIS just fine. From the logs I suspect that
webfolders is getting properties on the pcgi script or it's folder from IIS
and denying me based on that rather than looking at the full url.

Anyone know a way around all this?

A related question is, anyone know how to make MS-frontpage play nice with
Zope webdav?
