Symptoms
On a computer that is running Windows Server 2008 or Windows Vista, the system generates one of the following stop error codes and then restarts:
0x0000007F (UNEXPECTED_KERNEL_MODE_TRAP)
0x0000008E (KERNEL_MODE_EXCEPTION_NOT_HANDLED)
This problem typically occurs when multiple third-party network drivers are installed on the computer. For example, this problem may occur when the following drivers are installed:
-
VPN client drivers
-
Firewall drivers
-
Modem/ISDN drivers
-
Other network security filter drivers
Cause
This problem occurs because the Ndis.sys driver uses too much stack space in combination with several third-party network drivers. In this situation, a stack overflow occurs.
