You can stop or restart Cisco Secure ACS services as a group, except for
CSAdmin, using the Cisco Secure ACS HTML interface. For more information,
see Service Control, page 8-1.
Individual Cisco Secure ACS services can be started, stopped, and restarted from
the Services window, available within Windows Control Panel.
Windows Registry
The Cisco Secure ACS information is located in the following Windows Registry
key:
HKEY_LOCAL_MACHINE\SOFTWARE\CISCO
Unless you are advised to do so by a Cisco representative, we strongly recommend
that you do not modify Windows Registry settings pertaining to Cisco Secure
ACS.
Warning
Do not modify the Registry unless you have enough knowledge and experience
to edit the file without destroying or corrupting crucial data.
CSAdmin
CSAdmin is the service that provides the web server for the Cisco Secure ACS
HTML interface. After Cisco Secure ACS is installed, you must configure it from
its HTML interface; therefore, CSAdmin must be running when you configure
Cisco Secure ACS.
Because the Cisco Secure ACS web server uses port 2002 rather than the standard
port 80 usually associated with HTTP traffic, you can use another web server on
the same machine to provide other web services. We have not performed
interoperability testing with other web servers, but unless a second web server is
configured to use either port 2002 or one of the ports within the range specified
