ID: Q166003


The information in this article applies to:
  • Microsoft Internet Information Server versions 2.0, 3.0


SUMMARY

Internet Information Server (IIS) allows an administrator to grant or deny access to a Group of Computers based on Network ID and Subnet mask.


MORE INFORMATION

The advanced property page on the WWW, FTP, and Gopher services has two security options. By default, all computers will be: Granted Access or Denied Access.

The Except Those Listed Below: dialog box allows you to specify Single Computer or Group of Computers that access information. After you select between Granted Access and Denied Access for all computers, click the Add button. Depending on which option you selected, the Deny Access On or the Grant Access On dialog box is displayed.

The Single Computer option allows you to enter a single IP address. The Group of Computers option allows you to enter the Network ID and the Subnet Mask. You must specify the first IP address in the range of IP addresses available for the Network ID along with the Subnet mask.
