In Windows Vista or later version, after you map a WebDAV shared drive, such as a SharePoint document library, you are required to type your password every time you open it. Clicking the Remember Password checkbox seems to have no effect. Additionally, you get an Unable to connect to network drive message when you start the computer. This is particularly a problem when the WebDAV share is located outside of your local network (on the Internet).
When you check the Remember Password box, Windows is actually saving your password. You should be able to see it in your Credentials Manager Control Panel. The problem is that as a security feature Windows does not allow this password to be sent automatically (This only applies to WebDAV shares that are outside your local network.)
With a little registry editing, however, we can set the system to allow saved passwords to your external WebDAV servers.
Important: modifying registry incorrectly can cause damage to your computer, so always back up your registry first by using the export command with the registry editor.
