3. If the HP-UX AAA Server received the request and remained unresponsive, but
did not log an error in the logfile, see “Troubleshooting External Services”

1. Verify that the DNS server is available by entering the nslookup command. For
more information on the nslookup command, see nslookup(1M).

configured to send requests to the correct HP-UX AAA Server.

(page 351) to check for proxy server failures.
