Download OpenAFS for Stanford

Download OpenAFS for Windows

To tell if your computer is running a 32-bit or 64-bit version of Windows:

  • Windows 8 and Windows 10 —right-click Start and click System.
  • Windows 7 — click the Start button, right-click Computer, and then click Properties .
  • The system type is listed in the System section.


  • To use OpenAFS,  you need to authenticate with  Kerberos for Windows or Kerberos Commander (Mac).
  • If your need is to occasionally update your personal or department web page then you will likely be better off using an SFTP client like SecureFX (Windows) or  Fetch  (Mac).
  • You must have administrator privileges on the computer to install Stanford OpenAFS. If you do not have administrator privileges, ask your system administrator to install Stanford OpenAFS for you.
  • If you're using an AFS client behind a firewall or port blocking system of any kind, open up port 7001 for incoming UDP traffic. Otherwise, AFS will not work and it can tie up resources on the AFS file servers. If you're behind a firewall where you cannot do that, such as in a corporate environment, you won't be able to use AFS. If you need help, contact your system administrator, call the Stanford IT Service Desk at 5-HELP (650-725-4357), or submit a HelpSU request .

Notes for Windows users

  • After a major update to Windows 10 (an update that changes the build version), you may not be able to mount AFS volumes. To resolve this issue, you'll need to uninstall the OpenAFS client and then reinstall it. See Windows 10 Known Issues for more information.
  • Client for Microsoft Networks must be installed and enabled. To check for Client for Microsoft Networks:
    1. Open Network Sharing Center control panel by clicking the Start button and navigating to Control Panel > Network and Internet (category view) > Network and Sharing Center.
    2. Click the Local Area Connection you are using.
    3. In the Status dialog box, click Properties.
    4. In the Properties dialog box, Client for Microsoft Networks should be checked.

Notes for Mac users

  • An Extras folder is included with the OpenAFS software for Mavericks, Yosemite, and El Capitan. For Mavericks and Yosemite, this folder contains two files used for uninstalling OpenAFS. You need to run both files to successfully uninstall OpenAFS. For El Capitan, the folder contains one file. The uninstallers are from (not Stanford) so you may see a message saying that the files cannot be opened because they are from an unidentified developer. To open a file,  press CONTROL + click the file name and then click Open.
