Anonymous access is permitted Turning off anonymous access in server document of Notes Name & Address Book has no effect for the cgi-bin directory: anonymous access is still permitted.

If Domino is launched as a NT service, the service will not stop completely; you need to kill remaining processes (using kill.exe in Reskit) or reboot Windows NT. Not all requests crash the server, but sending: GET /cgi-bin/... (800 .) aaaa (4000 a) HTTP/1.0 Kills the HTTP executable every time. Both
