You are the network administrator for your company. The network consists of a single Active Directory domain. All servers run Windows Server 2003. The network contains a Web server that runs IIS 6.0 and hosts a secure intranet site. All users are required to connect to the intranet site by authenticating and using HTTPS. However， because an automated Web application must connect to the Web site by using HTTP， you cannot configure the intranet site to require HTTPS. You need to collect information about which users are connecting to the Web site by using HTTPS. What should you do？（）

A. Check the application log on the Web server.
B. Use Network Monitor to capture network traffic on the Web server.
C. Review the log files created by IIS on the Web server.
D. Configure a performance log to capture all Web service counters. Review the performance log data.
