Assume that you have a VPN server that is running in Windows 8.1 or Windows Server 2012 R2. When there is a high volume of client connections to the VPN server and large amounts of traffic between clients, the VPN server may crash. Additionally, you receive a Stop error message that resembles the following:
STOP: 0x0000001E (parameter1, parameter2, parameter3, parameter4)

  • The Stop error 0x0000001E describes the KMODE_EXCEPTION_NOT_HANDLE issue. 
  • The parameters in this Stop error message vary, depending on the configuration of the computer.
  • Not all 0x0000001E Stop errors are caused by this issue.


This issue occurs because the third-party VPN plugin support feature does not correctly handle the Secure Socket Tunneling Protocol (SSTP) miniport.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
