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.
I have the problem also on my own Notebook. When i work in Home Office it appers on any Connection. When i work in my Office there ist no Problem.
My Work around for Home Office is in the Moment that i us my Local Admin Acxount for the first login. Than i can log off and Log in to my Domain Account wirh no Problems.
This issues seemed to occur for any computers relying on user profile redirection that were updated to the Win10 2004 update. If the computer is booted with no network connectivity, upon sign-in the computer bluescreen's, giving an error referencing mrxsmb20.sys and rdr_file_system.
I found that if you connect to a network before sign-in the issue does not occur. I connected via wired connection. I am not sure if connecting via WIFI would also work. I am likewise not certain if you are required to actually connect to the network that actually allows profile redirection or if it can just be ANY network. The first time I wired into the redirection network and then could not get the issue to reoccur afterward, so I am not certain on the network type requirements at all.
It seems like you only need to do this once because I could not replicate the issue afterward.
Hello, we have the same problem. We have activated the folder redirection to our server. Since the desktop and the other profile folders are located there, there is no option to disable offline sync. Because our Notebook User work over VPN and they need the Offline Copy.
I also did some Tests with the Insider Build but the Problem still exist with Build 20152
Same problem here with all my upgraded Workstation. Also the newest and fresh installed ones.
Getting the same BSOD, mrxsmb20.sys rdr_file_system when users logon with domain account and have folderredirection enabled
tested this on multiple setups
Hope that a fix will be available ASAP.
