On your Microsoft Windows SharePoint Services team Web site, when you try to view documents in a document library in Explorer view, you may not be prompted for your credentials, and the Web page may not be displayed correctly. Microsoft Internet Explorer may display a blank, white Web page. Or the Web page may display the words "Action Cancelled."
This issue occurs if you are using Microsoft Windows XP or later on the client computer and the WebClient service is disabled.
To work around this issue, enable the WebClient service on the client computer. To do so, follow these steps.
Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.
Click Start, right-click My Computer, and then click Manage.
Expand Services and Applications, and then click Services.
In the right pane, double-click WebClient.
Click the General tab.
Do one of the following:
To configure the WebClient service to start automatically when the computer starts, click Automatic.
To configure the WebClient service so that you start the service manually, click Manual, click Apply, and then click Start.
Note When you configure a service to use a manual startup type, the service does not start automatically when the computer starts.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section of this article.
