Use this tab when making decisions on whether to prohibit a Web service extension. If you prohibit the current Web service extension, the applications in the Used by list might stop working correctly and other applications (not listed in this dialog box) may stop working as well. It is also possible that Internet Information Services (IIS) may not detect other dependencies that could stop applications from running correctly.
This is a list of applications known to use the designated Web service extension, identified at the top of this tab.
To learn more about Web service extensions and configuring applications, see the IIS 6.0 online documentation on the Microsoft Windows Server TechCenter.
