[Zope] WebDAV Functionality Question

Hello, I have Zope (2.5.1) installed and have the WebDAV server set up ( -W 8088) and working. I am using win2k web folders to connect to the webdav server. I can connect and browse just fine, but I get an error when I try copy a file from my win2k box to the server. Has anyone found a way around this. Thanks. Patrick
