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.

Mine BSOD when they're online with access to a DC.
I'm thinking something got lost in translation. Their change logs always value terseness over presentation of useful information. I'm still crossing my fingers that this is the one we've been waiting for.
Maybe they mean "device that is not currently connected to the domain".
Hope it sticks!
From November 30, 2020—KB4586853 (OS Builds 19041.662 and 19042.662) Preview (microsoft.com):
The 0x27 reference looks promising...but what follows doesn't sound like our problem. In fact, what follows "0x27" doesn't make much sense at all to me.
I think all of our devices are probably "in the domain". Mine certainly are.
This update KB4586853 appears to have resolved our issues also. only a few machines so far, but its looking good. All previous GPO and drive mappings now working as expected.
many thanks
Hi,
I've installed KB4586853 today and it seems to have resolved the issue.
I can now build, capture and deploy a Windows 10 Education x64 20H2 image with all my GPOs (including mapped drives and enabling offline files) in place.
Thanks,
Matt
