2, right key to publish the website folder, choose "Security"-"edit"-"Add"-"advanced"-"immediately inquires"-"select" IUSR users, and then save;

Windows 2008 R2 is much more complex to set than the previous version.

The first problem I've encountered is

401-Not authorized: Access is denied because the credentials are invalid.

Solve:

.1 website's home directory, the user is assigned to the Iis_iusers group (anonymous user selects the application pool label, the user defined in the logo)

.2 Group Policy, which allows iis_iusers to access the computer from the network

System Operating Environment: Windows Server 2008 + SQL Server 2008 + IIS Problem Resolution:

If your file is in NTFS format, most of the reason for the 401 error is due to the folder permissions in the directory that the site points to, set the appropriate folder permissions

The permissions area of the IIS site is divided into two, one is the page execution permission, and the other is the application pool execution permission. In general, this problem can be resolved by giving the site Directory IIS_IUSRS the user group's execution permissions.
