A: In Windows XP creating the DWORD registry value HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\KeepRasConnections and setting to 1 would keep Remote Access Service (RAS) connections open even after a logoff. This no longer works in Windows Vista and later. However, all that has really happened is the key has changed. For Windows Vista and later, perform the following:

  1. Start the registry editor (regedit.exe).
  2. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters (if the key doesn’t exist, create it).
  3. Create a new value called KeepRasConnections of type REG_SZ.
  4. Set the new value to have a value of 1.
