SYMPTOMS
On the Home Directory tab in the Browse For Folder dialog box, mapped drives appear in the drive list even though they cannot be selected. When you click a mapped drive in this list, OK is unavailable.



CAUSE
Starting with Internet Information Services (IIS) 5.1, you cannot select a mapped drive as the home directory location for a Web site or a virtual directory. In earlier versions of IIS, you can select a mapped drive, but it is then changed to the UNC path for the mapped drive.



STATUS
This behavior is by design.



MORE INFORMATION
Microsoft does not recommend that you use mapped drives for Web sites and virtual directories in IIS.

Steps to Reproduce Behavior

 * 1) Create a mapped network drive.
 * 2) Open the Internet Services Manager (ISM).
 * 3) Expand the local computer, and then expand Web Sites.
 * 4) Right-click Default Web Site, and then click Properties.
 * 5) On the Home Directory tab, click A directory located on this computer.
 * 6) Click Browse to open the Browse For Folder dialog box.
 * 7) In the drive listing, click a mapped drive. Note that OK becomes unavailable.
