Hi,
To further expand off of MooMoo's reply, 0x40000080 is the NDIS driver bug check for Windows 2000 and XP based systems. It's 0x7C on future generation OS'.
ndis.sys (Network Driver Interface Specification driver) routine call. The Network Driver Interface Specification (NDIS) is an application programming interface (API) for network interface cards (NICs). The NDIS forms the Logical Link Control (LLC) sublayer, which is the upper sublayer of the OSI data link layer (layer 2). Therefore, the NDIS acts as the interface between the Media Access Control (MAC) sublayer, which is the lower sublayer of the data link layer, and the network layer (layer 3).
The NDIS is a library of functions often referred to as a "wrapper" that hides the underlying complexity of the NIC hardware and serves as a standard interface for level 3 network protocol drivers and hardware level MAC drivers. Another common LLC is the Open Data-Link Interface (ODI).
With that said, as MooMoo already stated, update your network drivers ASAP.
Regards,
Patrick
