HTTP WARNING: HTTP/1.1 401 Unauthorized

[Steve Shipway]

>My HTTP check on a windows 2003 IIS 6 server suddenly started reporting the
following.  >HTTP WARNING: HTTP/1.1 401 Unauthorized 

Your web server being monitored is giving an 'unauthorised' to your check
command.

This is probably because the IIS6 server has been reconfigured to require
authentication to view the page.  Since you get the same from lynx (and not
a prompt for uername/password) I would guess that someone has configured it
to require the 'Evil-Microsoft-NTLM' Authentication...  nothing can support
this sort of authentication except IE due to various patents and secrets
(and the fact that it hooks into your windows client).  Get the IIS6 admin
to enable normal authentication as well or instead, or disable
authentication altogether.  You can pass auth credentials to the check_http
plugin, if necessary, but it can only support basic authentication.
