I fixed the problem, but I hope I didn't break something else in the process. I selected Default Web Site in IIS and clicked on Authentication. Then I right-clicked on Anonymous Authentication and selected Edit. Then I changed it from Specific User (IUSR) to Application Pool Identity.
I had the same problem so I solve it as you, And nothing goes wrong after
Few weeks ago I got this issue, then I was tried to solve as you mentioned by change the Specific User (IUSR) to Application Pool Identity.
and after that the system could run normally.
Recently I did IISRESET on this LD web server because there's some changes on my landesk configuration (process, window, query, dashboard, etc), But after IISRESET I was facing same error message again which is "The request failed with HTTP status 401: Unauthorized.", and all users could not login by using Console, but webdesk was still able to accessed and working properly with no error.
For the time being to solve the issue, I did restarted on LD web server and everything OK all user could be able to login LANDesk by using Console.
Did you facing recurrent issue like this after change the Specific User (IUSR) to Application Pool Identity? Do you know what is the root cause of this issue?
so that in future we know how to prevent it.
Thanks for any comments,
I never had any more trouble with this. It only happened the one time. I don't know exactly what caused the problem in the first place.
