Suppose You create an XML Web service named Time ESService. Each time ESService is started, it
checks for the existence of an event log named Time ESServiceLog. If TimeServiceLog does not
exist, Time ESService creates it. You discover that when Time ESService creates Time
ESServiceLog, it throws a System.Security.SecurityException. The exception includes the
following message: "Requested registry access is not allowed". You need to resolve this problem.
What should you do?
A. Configure Inetinfo.exe to run as the local administrator user account.

specified by Internet Information Services (IIS).
D. Modify the permissions of the
KEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesEventlog registry key to give
full control to the IUSR_computername user account.
