Good morning, I am having an issue on some PCs recently after some PCs received the Windows 10 2004 build update. After receiving said update, the machines will BSOD with a 0x027 error code when logging into a domain profile while connected to the network.
If I remove the network cable from the PC and log into a domain account that was cached on the machine before the update, it will log in without issues and then I can connect it to the network and it seems to resume function. I can also sign into a local account on the machine, with and without network connectivity.
I used Bluescreen View to look at the dumps which seem to be showing rdbss.sys and mrxsmb20.sys as drivers that are causing the issue. I have tried updating network drivers etc from the vendors websites and not relying on Windows to, but am still having the issue.
The other bizarre thing is if the PC crashes 3 times, boots into the recovery mode to try and repair your PC and I restart it, it will then log in once to a domain account and seem to be functioning, however if the PC is restarted it will BSOD on log in.
Has anyone seen or heard of any issues like this since this update? Could it be something out dated on the server that is causing the issue to happen to the machines on the newer OS? I can't help but feel like it has something to do with folder redirection and that is why cached accounts will work with no network connection however I am stumped how to get around this other than not updating every other machine, and rolling back if possible (I had a PC that was upgraded from Windows 7 to 10 and went straight to the 2004 build and BSOD'd, I tried to roll back to Win7 and system will not boot at the moment saying it is missing system files etc.).
I have some mini dumps I can share if that would help as I would like to get to the bottom of this if possible.
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.
Is there are available "Official" Microsoft statement visible somewhere on the issue, and when a fix will be released, or what the KB is / will be?
I've read somewhere that this is due 3rd week of Nov, today is monday of the third full week of Nov - is the patch coming?
So far I kept policy to delay upgrades for 180 days. Obviously this is not sufficient do to MS ignoring problems.
Why do they have insider testing and diagnostic reporting if they completely ignore the feedback?
Idiots. And on the top of everything - this problem seems to be too easy to reproduce.
Removing the drive letter mapping to networks hare indeed resolves the issue.
I got it working by entering safe mode with no network functions enabled and remove the drive map and reboot.
KB4586781 does NOT solve the problem for me!
I believe the correct KB is KB4586781.
I do see KB4586781 https://support.microsoft.com/en-us/help/4586781/windows-10-update-kb4586781
It doesn't say anything specific to this problem, but if others have had success I'll give it a try. Thanks for the correction Thrill31.
