The Windows user account that defines the user context for this process will
need read permissions on the following registry key in order to enable
reading from the system event log:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Security.

If you're not sure how to verify or change permissions on a registry key,
see http://support.microsoft.com/default.aspx?scid=kb;en-us;310426.

If you're not sure how to verify or change the user context for your web
application, see
http://msdn.microsoft.com/library/en-us/dnnetsec/html/SecNetAP05.asp.

HTH,
Nicole
