NDIS_INTERNAL_ERROR

NDIS internal network stack failure for NDIS_INTERNAL_ERROR

NDIS_INTERNAL_ERROR is bug check code 0x0000004F.

This bug check belongs to NDIS, the Windows kernel networking driver framework. The failing component is usually a miniport, filter, lightweight filter, protocol driver, virtual switch, VPN, firewall, packet-capture, or offload path that broke NDIS state.

How to read it in a dump

Use the stack and NDIS verifier output to identify whether the crash is in send, receive, reset, pause, restart, power, or NBL ownership.
The first parameter is usually the NDIS-specific subcode to interpret with symbols and documentation.
This is a driver-model failure, not an IP routing or DNS error.

What to check

Enable NDIS verifier and Driver Verifier for the NIC, virtual switch, VPN, firewall, and packet-capture drivers.
Check recent NIC driver updates, offload settings, teaming, virtualization, and filter-driver ordering.
Inspect NET_BUFFER_LIST ownership and completion paths.
