  1. Free virtual memory by closing unused applications.
  2. Restart the Server for NIS service.
  3. Restart the computer on which the error was generated.

  2. In the Results pane of the Services MMC, double-click Server for NIS .
  3. In the Service status area of the Server for NIS Properties dialog box, verify that the Server for NIS service shows as Started.
