ok, i solve the problem like this:
To enable Integrated Windows authentication
In IIS Manager, right-click the Web Sites folder, Web site, directory,
virtual directory, or file, and click Properties.
Note Configuration settings made at the Web Sites folder level can be
inherited by all Web sites.
Click the Directory Security or File Security tab, depending upon what level
you are configuring security settings.
In the Anonymous access and authentication control section, click Edit.
In the Authenticated access section, select the Windows Integrated
Authentication check box.
Click OK twice.
