Instructions Unzip the sample code to a directory underneath the root Web site home directory called wsa. For example, extract the sample code to c:\inetpub\wwwroot. The zip file contains a predefined path of “wsa” for all of the sample code, so the following directories will be created: c:\inetpub\wwwroot\wsa\Authenticate c:\inetpub\wwwroot\wsa\WebApp c:\inetpub\wwwroot\wsa\ThickClient c:\inetpub\wwwroot\wsa\CryptoWrapper Using the Internet Services Manager (ISM), change the Authenticate and WebApp directories into virtual directories. Navigate to the two directories in ISM, select Properties on each, and in the Directory tab, hit the Create button. Double-click the WebServiceAuthentication.sln file in the c:\inetpub\wwwroot\wsa directory, and press F5. You must customize the Authenticate\web.config file to suit your own environment, as described in the “Authenticate Windows Users” section of the article.
