Troubleshooting the Active Directory (AD) Connection

The numbered list below provides general troubleshooting recommendations to resolve problems with AD.


  1. Confirm that your NAS is running the latest NAS OS firmware (see Support.
  2. Check the Hardware monitor page to review CPU usage (see Hardware Monitoring). You can experience AD connection problems if the CPU is running high. Actions or jobs that can burden the CPU include:
    1. RAID synchronization (in this case, wait until the RAID is built)
    2. Multiple download jobs are running (stop or wait until download is finished)
    3. Multimedia reindexing (disable UPnP)
    4. Backup jobs are running (stop or wait until backup jobs are finished)
    5. Multiple simultaneous data transfers to/from the NAS from computers on the network (wait until the transfers are complete)
  3. Make sure the product is assigned the correct date, time, and time zone (see General Settings). A time discrepancy of more than five minutes between the domain and the 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.

  4. Make sure that the DNS server address provided to the NAS is a domain DNS, not an internet DNS provided by an internet service provider (see Network). The NAS must connect to the local network domain, not to a server on the internet.

    The NAS must be assigned a DNS server IP address on the local network configuration since joining a domain is based upon DNS resolution. To verify that the NAS is using a DNS IP address, try to ping the DNS server from a computer on the same network.
  5. General Settings > Workgroup/Domain (see General Settings):
    1. Enter the domain's Full Qualified Domain Name (FQDN). For example: (Active Directory Users and Computers Tool on Primary Domain Controller)

    2. Administrator login: The AD's administrator username.
    3. Administrator password: The AD's administrator password.
  6. Advanced criteria (optional).
    1. Server Name is the Domain Controller Host Name
    2. Server IP is the Domain Controller IP


Active Directory

The AD administrator can check the following:

  1. Verify if Kerberos Server & Time Server are registered in the domain DNS, allowing the LaCie NAS to connect. Kerberos Server & Time Server need to be accessible to the NAS, as these servers are involved in the joining process.
  2. Confirm that the machine name object is placed in the right container (not the default “computer” container) and check access rights for the machine name (such as who can log on). If necessary, delete the machine name in order to reset the object in AD.

    The domain administrator can create a computer account in AD and place it in the right container prior to joining the LaCie NAS to the domain (the computer account name is the NAS's name).
  3. Sub-domains can create problems when joining a domain. Confirm that the proper domain is being used and review the machine name object location/rights. As well, see if the user belongs to a different sub-domain. If so, review the user's rights to determine if there is an authorization conflict that prevents access to the NAS.
