For security reason we changed the administrators password on the domain(as we want to get away from using it it at all) Since then i am having NTDS errors on both DC's and also SAM errors reported in the event log. I have checked services.msc for any accounts that may have been using the admin account and there is nothing. I also have check Google but with no luck.

Below are the errors can anyone help me please?


Source NTDS Replication Event ID 1083 and 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
Network address:
1c0d18cc-9d4b-4baf-a2a8-9b08100adae9._msdcs.****.SCH.UK

This operation will be tried again later.


Source SAM Event ID 12294

The SAM database was unable to lockout the account of Administrator due to a resource error, such as a hard disk write failure (the specific error code is in the error data) . Accounts are locked after a certain number of bad passwords are provided so please consider resetting the password of the account mentioned above.
