On a computer has Windows Internet Explorer 7 installed, you create a disconnected network drive by running the subst command at a command prompt. When you open this network drive in Windows Explorer, it appears as Disconnected Network Drive. Additionally, the security zone for the network drive appears as Internet in the status bar.

However, on a computer that has Internet Explorer 6 installed, the security zone of the network drive appears as Local Intranet in the status bar.

Note This behavior also occurs if you map a network drive by using the system context.

This issue is caused by a design change in Internet Explorer 7.

When you map a network drive, the operating system tries to obtain the name of the network share so that the operating system can determine whether the security zone of the network share is Internet or Intranet. This action may fail when you use the subst command or when you map a drive in the system context. If the operating system cannot obtain the share name on a computer that has Internet Explorer 7 installed, the system sets the security zone of the network share to Internet. Therefore, this problem occurs.

By contrast, if the operating system cannot obtain the share name on a computer that has Internet Explorer 6 installed, the system sets the security zone of the network share to Local Intranet.
