Johannes also figured out that Windows XP can connect to our server via WebDAV: just add a new DWORD value to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters called UseBasicAuth and set it to 1. Then, as so often with Windows, you have to reboot. It still won't work via command-line, but Explorer's Tools>Map Network Drive... will be able to connect (but make sure that you use http://<server> notation rather than \\<server>, and that you specify proper credentials via different user).
