I keep getting this error and its filling up the Security Event Viewer logs. I also checked out the services on this server and could not find any thing that uses the mwadmin Credentials. Any Suggestions ? Pre-authentication failed: User Name: MWAdmin User ID: MWPOWER\mwadmin Service Name: krbtgt/mwpower.org Pre-Authentication Type: 0x2 Failure Code: 0x18 Client Address: 127.0.0.1

Hi, Thank you for your post. The event show mwadmin account using wrong password, please perform following steps to troubleshooting: 1.Check "logon Details" for all service, find the mwadmin account and update the password. 2.Check Schedule Tasks which run with mwadmin account 3.Restart Windows to Safe Mode or Clean Boot to check if any third party application is configured to use mwadmin account 4.Using Account Lockout and Management Tools to troubleshoot account lockouts and to change a user's password If there are more inquiries on this issue, please feel free to let us know.Regards, Rick Tan
