Wiki and Forum Articles for Linkstation Pro


  • Simplified File Sharing For Home or Small Office Network
  • Active Directory Support: Works as a client in an Active Directory domain allowing LinkStation Pro to utilize the domain users and groups. [Feature does not appear to function if domain controller & Linkstation are not on the same subnet. Support could not explain why NTP and Active Directory could not work across an IPSec VPN tunnel to the domain controller]
  • High Speed Processor, DDR-II Ram, and SATA Hard Drive Provide Ultra Fast Transfer Rates.
  • Control Access With Group and User Level Security
  • Access Data from any Windows or Macintosh Computer on Your Network
  • Two or More LinkStations Can be Used to Back Up Each Other Over Your Network
