Troubleshooting the Active Directory Connection

Thousands of different network and domain configurations exist, so these troubleshooting tips are necessarily general. However, checking the following points could help.

Product / LAN Side

  1. Make sure that the latest product operating system has been installed. Check Downloads.
  2. Make sure no heavy load processes are running (not mandatory but could help), for example:
    1. No RAID construction is running (wait until RAID is built)
    2. No multiple downloads are running (stop or wait until download is finished)
    3. No multimedia database building (disable Multimedia)
    4. No backups running (stop or wait until backups are finished)
  3. Make sure all users are disconnected from the product (not mandatory but could help) and that no heavy data transfers are taking place simultaneously.
  4. Make sure the product is assigned the correct date, time, and time zone. The reason is that a time discrepancy of more than five minutes between the domain and product may prevent or cause disruptions to the Active Directory (AD) connection. This tolerance is defined in Domain Controller Policy, and the default value is usually five minutes.

    The most precise way to set the product's time is to use the NTP Server feature in the Dashboard - General Settings widget. It can also be set manually from this page.
  5. Make sure that the DNS server address provided to the product is a domain DNS, NOT an internet DNS (as may be provided by an internet provider).

    The product must connect to the local network domain, not to a server on the internet.

    It's important that the product be assigned a correct and reachable DNS server IP address on the local network configuration, because joining a domain is based on DNS resolution. Verify the DNS IP on another computer on the same network as the LaCie product. From this computer, attempt to ping the DNS server.
  6. Dashboard: Domain Configuration window settings:
    1. Enter the domain's Full Qualified Domain Name (FQDN). For example: (Active Directory Users and Computers Tool on Primary Domain Controller)
    2. Admin login: Use the AD's administrator username.
    3. Admin password: Case sensitive.
  7. Optional Advanced Criteria can be input to help with joining.
    1. Server Name is the Domain Controller Host Name
    2. Server IP is the Domain Controller IP

All the above points must be verified, including the next section about configuring the AD to ensure correct Domain joining. Any incorrect configuration can cause the connection to fail.


Active Directory / Domain Side

On the Active Directory / domain side, the following points should be checked by the Active Directory administrator, as configuration is different for every customer.

  1. Ask the AD administrator to verify if Kerberos Server & Time Server are registered in the domain DNS, in order to allow the LaCie product to connect. Kerberos Server & Time Server need to be accessible to the LaCie product, as these servers are involved in the joining process.
  2. Check the machine name object in AD. Check that it's placed in the right container (not the default “computer” container) and check access rights for the machine name (such as who can log on to it). You may also need to delete the machine name in order to reset the object in AD.

    It may be necessary for the domain administrator to create a computer account in AD in the right container prior to joining the LaCie product in the domain (with the computer account name being the product's machine name).
  3. There may be an issue when joining a domain if a sub-domain has been set up. The question to ask is whether the domain joining was done using the correct domain/sub-domain name. (Again, check the machine name object location/rights in AD). Could the user belong to a different sub-domain not authorized to access the product?

Note: If the LaCie product fails to connect to a properly configured AD, you should provide LaCie technical support with the domain network configuration log from the Dashboard - Support page for analysis.
