If anyone out there is having issues joining a TeraStation III (or TeraStation Duo) to Active Directory, check to see if you have port trunking and Jumbo Frames enabled. I had everything configured correctly, but with those two features enabled it wouldn't work. Once port trunking and Jumbo frames were disabled I was able to authenticate. After I was able to join, I had to re-enable those two features and then everything was working. Hope this helps!
I have a Linkstation but I'm having the same problem. Where would I find these settings?
Does your domain controller require Digitally Signed SMB Packets? On Windows 2003 Server these policies are enabled by default. They need to be set to 'Disable', not 'Enable', or 'Not Defined'. If not I would initialize the unit and set it back up. Make sure the settings are correct:
Configuring the Buffalo Nas for Active Directory:
A computer account with the name of the Buffalo NAS needs to be created on the domain. It needs to be configured so that a pre-2000 machine can use this account.
In "IP Address Properties" under "Network", the DNS server address needs to be set to the Domain Controller's address.
The clock on the Buffalo needs to be set to the same timezone as the Domain Controller and the times need to be with in 5 minutes of each other.
The "Workgroup/Domain" page under "Network" needs to be set to the following settings - If ever a field is too short to enter the full information (particularly the Domain Name and the Domain Controller fields) they need to be filled in as much as possible:
Workgroup and Domain Properties:
Network Type: "Active Directory"
Active Directory Domain Name (NetBIOS Name): NETBIOS Legacy Domain name, ex. "DOMAIN"
Active Directory Domain Name (DNS/Realm Name): Full Domain name, ex. "domain.com"
Active Directory Domain controller Name: Domain Controller name, ex. "server"
AD Administrator Name & AD Administrator Password: The user name and password of an account with administration privileges so the Buffalo can properly be added to the network. This information will not be stored.
WINS Server IP Address: IP address of the WINS server (if not using WINS, enter domain controller's IP address)
