Event ID : 680 every ten minutes.

Medium Priority
Last Modified: 2013-12-04
Dear All,

I'm going through a server log and I've been getting a lot of Event ID : 680s.
The thing I noticed about these messages were that they are exactly 10minutes apart.
eg. 4:15:22       4:25:22        4:35:22  --- and so on.
Does anyone have any idea what this can be?

 Logon account:      IUSR_SERVERNAME7
 Source Workstation:      SERVERNAME7
 Error Code:      0xC0000064

Thank you in advance

Hi chinguetti,

I believe you are describing Failure event? Does your website use Integrated Windows Authentication and if yes, what is the value of NtAuthenticationProviders in metabase.xml file?


Not the solution you were looking for? Getting a personalized solution is easy.

Ask the Experts

This error is basically an user authentication failure.
It seems that the user IUSR_SERVERNAME7 which is the IIS guest account of workstation SERVERNAME7 is trying to log-in or any other authentication requiered operation with the IIS.
Your options are:
1. Allow guest authentication on the IIS
2. Disable the process that keeps authenticate every 10 minutes
3. Configure that process to use a valid user credentials
For more info about your erorr message see:


I'm terribly sorry, I was looking at the wrong server!

toniur: yes, it's indeed a failure event.
oriziv: great reply, I'll look into it on server7.

On this server however, the time is randomized, but it's basically always the same three users who show up on the eventvwr. The Error Code being either 0xC0000071 or 0xC0000064 or 0xC000006A
 Logon account:      username
 Source Workstation:      PC918
 Error Code:      0xC0000071

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
Code 0xC0000071 means that the user's password has been expired, change the user's password and you won't see this message again.

Code 0xC000006A is a known issue of Win XP. You can disable the welcome screen on the problematic workstation or obtain the latest updates from microsoft.
In the article I recommanded in my first comment, go to the last post. It deals with this code.
