Site costed referrals are disabled on a domain controller.


If a domain controller becomes unavailable, client computers that are using the SYSVOL or Netlogon folders of the domain controller might fail over to a distant domain controller instead of a closer domain controller.


Use the Dfsutil command-line tool to enable site costed referrals on this domain controller.

To enable site costed referrals on domain controllers

  1. To open an elevated Command Prompt window, click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

  2. Type Dfsutil server registry sitecostedreferrals set*<servername>*, where <servername> is the name of the appropriate domain controller.
