[Nagios-users] HTTP WARNING: HTTP/1.1 401 Unauthorized

[Rene Nelson]

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

Does anyone have any suggestion as to the cause?  Thanks in advance for any help.

When going to the URL via lynx I get:

You are not authorized to view this page

   You do not have permission to view this directory or page using the
   credentials that you supplied because your Web browser is sending a
   WWW-Authenticate header field that the Web server is not configured to
   accept.

This worked fine until I restarted nagios today.  Any suggestions?
