Before an application can call a Web service extension, you must configure the application to make calls to that extension. A Web service extension can accept calls from more than one application.
You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /User:Administrative_AccountName "mmc %systemroot%\system32\inetsrv\iis.msc".
|To allow an application to call a Web service extension|
In IIS Manager, expand the local computer, and then click Web Service Extensions.
Click Add and allow extensions for a specific application.
From the Application list box, click the name of the application. The Web service extension that the application is allowed to call appears in the Extensions to be allowed box.
