More Problems since changind domainadministrator password.

[tosca925]

We have to change the domain\administrator password for security reasons. We rarely used the account but it did do some things.

 

I am getting lots of errors in event viewer now. One which is an earlier post which is NTDS replication settings.But i am also getting Failure Audits

 

Event ID 675 Pre-authentication failed:

User Name: Administrator

User ID: domain-name\Administrator

Service Name: krbtgt/domain-name

Pre-Authentication Type: 0x2

Failure Code: 0x18

 

Also

 

Event ID 1083&1955

 

Active Directory could not update the following object with changes received from the domain controller at the following network address because Active Directory was busy processing information.

 

Object:

CN=Administrator,DC=SCH,DC=UK

 

 

All this happened since the domain\administrator password has changed. I have googled with out much success.

Wow - you're not having much luck are you? What happens when you change back the administrator password?

Could you have any services running under the administrator account? For other accounts that will cause account lockout if you change the password but the service tries to use the old password; for domain admin, you can never lock out but you may get weird effects.

 

The Kerberos error you're seeing is mentioned at http://www.windowsecurity.com/articles/Kerberos-Authentication-Events.html and it seems to suggest that this is a "bad password" error
