A. Windows refreshes the domain list whenever the machine is locked for more than two minutes (120 seconds). This can lead to a delay while it does this until the user gets control of the system again.

You can modify the amount of time it waits until refreshing by performing the following:

  1. Start the registry editor (regedit.exe)
  2. Move to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
  3. Double click on DcacheMinInterval (or if it does not exist create of type REG_DWORD)
  4. Modify between 120-86400 seconds
  5. Click OK
  6. Close the registry editor
  7. Restart the computer
