Please report both new issues and existing issues that have been confirmed to be present or fixed in a specific redirector version to fax@greenbytes.de
The redirector functionality is implemented by means of MRXDAV.SYS. It usually resides inside "C:\WINDOWS\system32\drivers" To find the version, select the file in Explorer, choose "Properties" from the right-click context menu, then select the "Version" tab.
See Web Folder Client (MSDAIPP.DLL) Versions and Issues List for a known list of versions and issues in Microsoft's "WebFolder" client (this component predates Windows XP's WebDAV Redirector).
The WebDAV Mini-Redirector sends a User-Agent request header starting with "Microsoft-WebDAV-MiniRedir".

| name | description |
|---|---|
| basic-authentication (Ref: http://support.microsoft.com/?kbid=315621) | Basic Authentication is broken (the username is sent with the domain name). |
| no-basic-auth (Ref: http://support.microsoft.com/kb/841215) | Basic Authentication has been disabled for HTTP connections. This can be undone by changing a registry setting as described in the Knowledge Base article. Note that the machine needs to be rebooted after the change. |
| credentials-not-sent | It appears that credentials are only sent when the "/user" syntax of NET USE is used. Leaving the parameter out causes the command to prompt for the credentials, but they won't be used. |
| namespace-handling | DAV: namespaced elements in a PROPFIND responses can not use a default namespace; each element must be explicitly prefixed with a namespace prefix defined in itself or a parent. If a default namespace is used the client will give no errors, but will not display any resources. |
| port-handling | The redirector does not support HTTP URLs where a specific port number is specified. Network trace shows no outgoing request at all. |
| server-discovery (Ref: http://support.microsoft.com/?kbid=831805) | When connecting to a server, the redirector makes the incorrect assumption that the root of the URL namespace will be WebDAV-aware. Servers that do not behave like this (for instance by restricting WebDAV to a specific namespace partition) cannot be mounted. |
| custom-and-href (Ref: http://lists.w3.org/Archives/Public/w3c-dist-auth/2012AprJun/0000.html) | Custom properties using a DAV:href child element confuse the client; it uses the wrong DAV:href element to determine the display name. |
