Help troubleshoot failed logins

I am trying to troubleshoot failed login attempts from Computer X, there are over 70 failed attempts from this computer everyday . I have ran malware checks. What steps can I take to narrow down the offending behavior?

This is the log from the application server running server 2008 r2 standard.

Is there anything in the credential manager on the offending machine?

Are there any applications which would be using domain credentials on the machine whilst being open? Outlook or Citrix?

Have you tried dis-joining this machine from the domain and then re-joining it?

Maybe this might help:

Thanks for the reply, the PC is on the same network as the server, but there is no domain controller.

Is your machine not in a domain? Also have you checked the other things I mentioned.

Your credential management suggestion was a huge help!

There is a Himachi user that had some old credentials hanging out.
