Unable To Locate Domain Controller

(Article ID: 001139)
Summary

A Snap! Server running SnapOS is unable to load the usernames and groups in the local domain. The server logs have the following warning:

SMB : Domain controller unavailable. (Source: Network)

To fix this problem the machine name and IP address of a domain controller must be set.
NOTE: If the chosen domain controller is running Windows Server 2003 or higher then the Snap! Server needs to be running SnapOS version 4 or higher.

Step-by-step instructions

To set the machine name and IP address for a domain controller, do the following:

  1. Open a web browser to http://<Server DNS name or IP address>/config/debug.
    NOTE: The address may have to start with https if SSL is enabled on the server.
  2. Enter the username and password of a local user with administrative rights on the server.
  3. Type hosts DOMAIN IP xxx.xxx.xxx.xxx and click OK.
    NOTE: DOMAIN is the NetBIOS name of the domain and xxx.xxx.xxx.xxx is the IP address of the chosen domain controller.
  4. Type hosts DOMAIN machine SERVERNAME and click OK.
    NOTE: SERVERNAME is the NetBIOS name of the chosen domain controller.
  5. Type reboot time and click OK.
    NOTE: time is the number of seconds until the system restarts.

After the server has restarted, wait a few minutes for the server to authenticate with the domain controller and begin populating the domain SmbDomainGroups table. This can take ten minutes or longer for larger domains. To verify that the server is communicating with the domain controller do the following:

  1. Go the server's administration page (http://<Server DNS name or IP address>/config).
  2. Click on Security.
  3. Click on Network Shares.
  4. Select a network share and click Access.

The users/groups pane on the right should contain a list of domain users and groups as well as the users and groups local to the Snap! server. If there are no domain users or groups listed, go back to the server's administration page and review the server logs again.
