RSA ClearTrust Agent 4.6 for Microsoft Internet Information Services (IIS) 6.0

Microsoft Internet Information Services (IIS) 6.0 on Microsoft Windows Server 2003
IssueError: "Service Unavailable" in web browser when accessing Microsoft Internet Information Services (IIS) web server with RSA ClearTrust Agent 4.6 for Microsoft Internet Information Services (IIS) 6.0
Microsoft Windows event log shows:

"A process serving the application pool 'DefaultAppPool' reported a failure. The process id was 'xxxx'. The data field contains the error number. The error number is 80070005."
Microsoft Windows event log shows:

"Application pool 'DefaultAppPool' is being automatically disabled due to a series of failures in the process(es) serving that application pool."
RSA ClearTrust Agent 4.6 for Microsoft Internet Information Services (IIS) 6.0 appears not to start, and no ctagent.log file is created
ResolutionThis problem can occur if the file permissions on the ct_iis60_agent.dll are incorrect. Right click the ct_iis60_agent.dll file and select the security tab. Ensure that the file is owned by a user account under which the Microsoft Internet Information Services (IIS) server runs. The minimum requirement is that the file be owned with Read & Execute permissions by the Users object.

Also, this problem typically occurs if the .DLL file is copied from another server, and is owned by the Administrator of the original server. Right click the ct_iis60_agent.dll file and select the security tab. Click "Advanced", and check the "Allow inheritable permissions from the parent" object checkbox.

NOTE: The "Service Unavailable" error message in the web browser can be caused by any problem that prevents the IIS Application pool from starting. Examine the Windows event log to determine the cause of the failure.
