- You use Windows Explorer on a client computer that is running Windows 7 Service Pack 1 (SP1) to connect to a Distributed Authoring and Versioning (DAV) server.
- The DAV server is configured to Require client certificates or Accept client certificates from client computers that revert to other authentication methods. For example, the DAV server is configured for revert to Basic Authentication.
- You map a drive by using a user account that is not the default logon user account on the client computer. To do this, you use one of the following methods:
- You select the Connect using different credentials option when you use the Map Network Drive UI.
- You run the net use command together with the /User parameter.
- You have installed update 2727994 on the client computer, and one of the following conditions is true:
- There is more than one certificate that the user can select.
- There are no certificates in the certificate store on the client computer.

Hotfix replacement informationThis hotfix does not replace a previously released hotfix.
Note The default setting on an SAP DAV server is "Accept Certificate." Therefore, the server asks the client to transfer a certificate. When the client does not send a certificate, authentication is performed by using another method, such as Basic Authentication. In this situation, the DAV client should use Basic Authentication, even if you configure the DAV server Secure Sockets Layer (SSL) setting for client certificates to "Accept Certificate."
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
