Event Details

Product: Windows Operating System

Source: SAM
Version: 6.0
Symbolic Name: SAMMSG_REFRESH_FAILED
Message: SAM failed to restore the database to an earlier state. SAM has shutdown. You must reboot the machine to re-enable SAM.

Resolve

Restart the computer to enable the SAM database

The Security Accounts Manager (SAM) experienced a commit failure, and it also failed to revert to an earlier state. Ensure that the system drive is not completely out of free disk space, and then restart the computer. To enable SAM access again, you must restart the system. Perform the following procedure on the computer that is logging the event to be resolved.

To perform these procedures, you must have membership in Domain Admins, or you must have been delegated the appropriate authority.

To ensure that there is enough free disk space on the system drive:

  1. Open a command prompt as an administrator. To open a command prompt as an administrator, click Start. In Start Search, type Command Prompt.

  2. At the command prompt, type cd /d %systemroot%, and then press ENTER.
  3. Type dir, and then press ENTER. The last line of the command output displays the number of bytes that are free, which should be at least 10,024 or more. If there are not enough free bytes reported, remove unnecessary files from the System root drive.
  4. Restart the computer to enable the SAM database.
