网络驱动程序接口规范 (NDIS)(Network Driver Interface Specification (NDIS))是网络接口卡的编程接口，有助于计算机网络中系统驱动程序的正常运行。NDIS帮助计算机系统与计算机网络上的其他连接设备和硬件组件进行通信。相关地，ndis.sys是微软(Microsoft)为Windows操作系统开发的关键系统文件。系统文件或 sys 文件是 Windows 系统的重要组成部分，是Windows系统(Windows)用于与连接的硬件和设备进行通信的系统驱动程序设置的存储库
BUGCODE_NDIS_DRIVER
The BUGCODE_NDIS_DRIVER bug check has a value of 0x0000007C. This bug check indicates that the operating system detected an error in a networking driver.
ndis.sys 文件主要存储在驱动程序文件夹C:\Windows\System32\drivers中，它是操作系统正常运行所必需的。虽然不知道 ndis.sys 系统文件的存在会影响操作系统的正常运行，但一些Windows用户在他们的Windows系统上遇到了ndis.sys 蓝屏错误。(ndis.sys blue screen errors)蓝屏(Blue)错误通常发生在用户打开程序和功能时。当驱动程序在系统启动期间加载或可能在Windows关闭期间发生时，也会发生该错误。
ndis.sys 蓝屏错误的原因尚不清楚，但由于文件损坏、设备驱动程序配置错误、恶意程序、驱动程序错误、Windows注册表损坏、系统文件丢失或系统文件损坏，可能会出现此问题。如果您的硬盘损坏以及系统RAM损坏，也可能会出现(RAM)Ndis.sys错误。
在此类错误事件中，我们大多数人都尝试禁用 ndis.sys 文件。但是，这样做并不能解决问题，因为操作系统的正常运行需要 ndis.sys 文件，即使禁用 ndis .sys 后，该文件也会重新开始。此外，人们可能还希望暂时禁用安全软件，因为有时已知防火墙和防病毒软件会导致软件冲突。在本文中，我们解释了一些解决Windows 10上的 ndis.sys(Windows 10)蓝屏(Blue)错误的解决方案。随附的错误消息可能是 – DRIVER_IRQL_NOT_LESS_OR_EQUAL。

单击是并重新启动系统。
3]运行SFC扫描
System File Checker是一个命令提示符工具，可以扫描损坏的系统文件，包括 ndis.sys 文件以及修复损坏的系统文件。建议运行 SFC 扫描以修复有问题的系统文件。
4]运行CHKDSK
损坏的硬盘驱动器可能会导致 ndis.sys 蓝屏错误。CHKDSK扫描磁盘以检查是否有任何损坏的硬盘驱动器。
在开始菜单中搜索命令提示符。(Command Prompt)
右键单击命令提示符(Command Prompt)并从下拉菜单中选择以管理员身份运行选项(Run as administrator)
键入命令CHKDSK并单击Enter以检查您的磁盘。您可以运行以下命令：
chkdsk /f /r
重新启动系统。
5]运行DISM
要修复损坏的系统映像(repair a corrupt system image)，请在开始菜单(Start Menu)中搜索命令提示符(Command Prompt)。右键(Right)单击命令提示符(Command Prompt)并 从下拉菜单中选择以管理员身份运行选项(Run as administrator)
运行此命令 -
DISM /Online /Cleanup-Image /RestoreHealth
重新启动系统。
6]执行系统还原
执行系统还原可以将系统程序恢复到系统可能正常工作的时间。建议执行系统还原(System Restore)以修复蓝屏问题，该问题会将您的程序和系统文件恢复到Windows PC 正常工作的时间。
Hope something helps!
Fix ndis.sys failed BSOD error BUGCODE_NDIS_DRIVER
Network Driver Interface Specification (NDIS) is a programming interface for the network interface cards that aids in the 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 the Windows system to communicate with the connected hardware and devices
BUGCODE_NDIS_DRIVER
The BUGCODE_NDIS_DRIVER bug check has a value of 0x0000007C. This bug check indicates that the operating system detected an error in a networking driver.
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 Windows 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. Additionally one may also want to temporarily disable security software as firewalls and antiviruses are sometimes known to cause the software conflicts. In this article, we explain some solutions to fix ndis.sys Blue screen error on Windows 10. The accompanying error message could be – DRIVER_IRQL_NOT_LESS_OR_EQUAL.
Fix ndis.sys failed BSOD error
1] Update/Reinstall your PC Device Driver
Ndis.sys Blue screen error can occur if you are using an outdated network driver or corrupted drivers – notably NDIS miniport driver (Ndis.sys.. It is recommended to update your device driver to fix the blue screen error. On a related note make sure you update an appropriate device driver in order to fix the problematic drivers. Follow the below steps to reinstall the network device driver to solve the network driver issue.
Reboot the system in Safe Mode. Open Control Panel and navigate to Device Manager. Click on Network adapters and select the network device from the drop-down menu.
Right-click on the network device and click on Uninstall from the drop-down menu to uninstall the device driver.
Click OK to confirm and click on Scan for hardware changes to reinstall the driver.
If this does not help, you may consider rolling back your device driver.
2] Rollback Network drivers
Identifying the recently installed network drivers and then trying to restore the previous network drivers can help to fix the ndis.sys blue screen error problem.
Open Control Panel and navigate to Device Manager. Click on Network adapters and select the network device from the drop-down menu
Right click on the network device and click on Properties. Go to Drivers tab and click on Roll Back Drivers.
Click Yes and restart the system.
3] Run SFC scan
System File Checker is a command prompt tool that scans for corrupted system files including ndis.sys files as well as repair the corrupted system files. It is recommended to run an SFC scan in order to repair the problematic system files.
4] Run CHKDSK
The corrupt hard drive may lead to ndis.sys blue screen error. CHKDSK scans the disk to check if there are any corrupt hard drives.
Search Command Prompt in the Start Menu.
Right click on the Command Prompt and select the option Run as administrator from drop-down menu
Type the command CHKDSK and click Enter to check your disk. You may run the following command:
chkdsk /f /r
Restart your system.
5] Run DISM
To repair a corrupt system image, search for Command Prompt in the Start Menu. Right click on the Command Prompt and select the option Run as administrator from the drop-down menu
Run this command-
DISM /Online /Cleanup-Image /RestoreHealth
Restart your system.
6] Perform System Restore
Performing System Restore can resume your system programs back to the time when the system was potentially working perfectly. It is recommended to perform System Restore to fix the blue screen issue that would return your programs and system files back to the time when the Windows PC was working properly.
