I got the 2004 update yesterday and that went well enough otherwise but I am having a problem with the Windows Defender Antivirus Network Inspection Service that I did not have previously.
The Microsoft Defender Antivirus Network Inspection Service service depends on the Microsoft Defender Antivirus Network Inspection System Driver service which failed to start because of the following error:
The supplied user buffer is not valid for the requested operation.
Microsoft Defender Antivirus Real-Time Protection feature has encountered an error and failed.
Feature: Network Inspection System
Error Code: 0x8007042c
Error description: The dependency service or group failed to start.
Reason: The system is missing updates that are required for running Network Inspection System. Install the required updates and restart the device.
I've got this error repeatedly (3002).
Something is definitely wrong with the install of Windows Defender tho... Help? How do I fix this and stop the errors and get it reconfigured properly. Do I have to reinstall it?
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
4.18.2008.4 was ready, upon manual check for updates, for 2 of my machines. KB4566782 was available for all of my machines but it is a separate update and Defender 4.18.2008.4 is not rolled into it.
I am currently updating Defender on those other machines and will report back shortly.
The Defender update is KB4052623.
I have the same issue, and reported it here:
Defender Antivirus Network Inspection Service Fails to Start
Details:
\SystemRoot\system32\drivers\wd\WdNisDrv.sys failed to load
The WdNisSvc service depends on the WdNisDrv service which failed to start because of the following error:
The supplied user buffer is not valid for the requested operation.
At the same time I have a BIOS update issue which I reported here:
Aurora R7 BIOS v1.022 (July 2020) Won't Install
Details:
Can't update Dell BIOS. This July 2020 Dell BIOS update is a critical security update.
Aurora R7 BIOS v1.022 (July 2020) Won't Install
I've tried several times but can't get the Aurora R7 BIOS v1.022 (July 2020) to install.
When I run the BIOS installer it creates a file called amifldrv64.sys in the download directory then dies.
Here's the event viewer entry after trying to install it:
Faulting application name: Alienware_Aurora_R7_1.0.22.exe, version: 1.0.5.0, time stamp: 0x5a0e913f

Dell Forum Report: Aurora R7 BIOS v1.022 (July 2020) Won't Install
The BIOS issue is likely unrelated, and Dell should look into that urgently but I put it here just in case it is related because both of these issues are security related and they're both occurring at the same time for me.
I also had a critical BIOS security update that I was not sure if it was related or not, and performed at some point during my "process." My update went smoothly (fortunately). I only discovered that the update existed because I had to do the troubleshooting for the issue I was having. I had checked for BIOS updates about a month ago doing maintenance, and the date on the BIOS update was late July.
I can try to show you where it fit in.
* made bad decision to trust seeing no issues on 2004 update, and allowed update to proceed (yes, i did restore points and all that, i don't think it ultimately mattered)
* found issues in event viewer with 2004 update; dism and sfc report no issues ever
* multiple virus scans with multiple vendors, no issues
* troubleshoot and identify issue with wdnissvc
* post to get help
* realize that core isolation is also not working
* troubleshoot and try to get things working
* finally decide to try to roll back to before update
* attempt to revert to previous system fail, system will not boot
* do restore but save data option
* all SEEMS well, dism and sfc report no issues
* one of the things I install is OEM support tool -- find out about BIOS update needed
* UPDATE BIOS successfully, always fun (ha ha)
* other problems develop, signs of system corruption or who knows what
* clean install with assistance of microsoft support
I cannot say if your BIOS issues are or are not related. And I cannot advise of what to do since I am not a MS expert by any means. I've read that you should do BIOS updates before clean installs but if you can't get it done, I don't know. If you don't have a separate topic about this issue, you could start one and ask how to proceed.
I can confirm that Update for Microsoft Defender Antivirus antimalware platform - KB4052623 (Version 4.18.2008.4) has solved this issue for me on the machines on which the update was available.
WDNIS starts without issue with Memory Integrity enabled on those systems.
Thanks, but I know how to manage normal updates, which I performed August 11. Several posts seemed like people were downloading updates off the usual channel.
Oddly, KB4052623 (Version 4.18.2008.4) isn't in the official update catalog
