I need help, my system log keeps getting full due to constantly getting the following error message: THE SERVER WAS UNABLE TO LOGON TO THE WINDOWS NT ACCOUNT IUSER_SERVERNAME DUE TO THE FOLLOWING ERROR:
LOGON FAILURE: UNKNOWN USER NAME OR BAD PASSWORD. THE DATA IS THE ERROR CODE -
this is all that appears in the data section: 0000: 2e 05 00 00 ----
Note that servername was substituted for the name of the server
Why is this happeneng and how can I fix it????

It might be attempting an automatic login from the registry settings. Run regedit . Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon. See the AutoAdminLogon value? If it is set to 1, then windows will be trying to login automatically with the settings specified in other values in that key. Set it to 0 to disable this functionality. That may or may not fix your problem...

If you just want to keep your logs from filling, then disable auditing of failed logons.

Best of luck!

The IUser_server account is used for anonymous access to IIS services. If the account has been disabled or the computer generated password has been changed, you will get that error and will continue to get that error [because IIS needs it as part ofthe service and security authencation] until either the account is enabled or the password is reset to the original computer generated password.
