Network Driver Interface Specification (NDIS) is a programming interface for the network interface cards that aids in proper functioning of a system driver in a computer network. NDIS helps the computer system to communicate with other connected devices and hardware components on a computer network. Relatedly, ndis.sys is a critical system file that is developed by Microsoft for the Windows operating system. The system files or sys files are the essential part of the Windows system and a repository of system driver settings used by Windows system to communicate with the connected hardware and devices.
The ndis.sys files are mostly stored in a driver folder C:\Windows\System32\drivers and it is necessary for the normal functioning of the operating system. While the presence of ndis.sys system file is not known to affect the normal functioning of an operating system, some of the Window users have encountered ndis.sys blue screen errors on their Windows system. The Blue screen error usually occurs when users open a program and function. The error also occurs when the driver gets loaded during the system startup or may occur during Windows shutdown.
The cause for the ndis.sys blue screen error is not exactly known, but the issue may occur because of corrupt files, misconfigured device drivers malicious programs, bad drivers, corrupted Windows registry, missing system files, or due to the damaged system files. The Ndis.sys error may also arise if your hard disk is damaged and also if the system RAM is corrupted.
During such error episodes most of us try to disable ndis.sys file. However doing so will not fix the problem as the ndis.sys file is required for normal functioning of the operating system, and even after disabling ndis .sys, the file will start all over again.
