Symptoms
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)
Notes
-
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.
Cause
This issue occurs because the third-party VPN plugin support feature does not correctly handle the Secure Socket Tunneling Protocol (SSTP) miniport.
Resolution
To resolve this issue, install the November 2014 update rollup for Windows RT 8.1, Windows 8.1, or Windows Server 2012 R2.
Status
