  • Question

  • One member of staff gets BSOD errors when using files located over the network.

    Appears to be common in older Windows versions but does seem to carry on in version 1903, I am going to attempt a system rebuild and see how it then behaves with the same account setup.

    Issues happen for one member of staff, have recreated his profile, set it as an old one and tested other accounts on the same machine, issue only happens under one persons logon, new starter no roaming profile.

    I have upgraded this from 1809 to 1903 to attempt to update the system files this has reduced the frequency of the issue but it still persists.

    This was happening after opening a single document up to 5 documents on the network, now this can open multiple documents before triggering the error.
    I have cloned him onto a different machine (same make and model) no issue.
    Memtest and Windows memory diagnostic tool find no errors at all, soldered components so could swap out to see if a faulty part.

    Due to diagnostic software advising there are no issues on the machine at least in regards to RAM.

    Disabled SMB2 and re-tested no change.

    Checked for any hardware and OS updates, applied these and re-tested the issue hasn't changed.

    CHKDSK no errors detected (NVME drive if this makes any difference).

    The crash took place in a file system driver. Since there is no other responsible driver detected, this could be pointing to a malfunctioning drive or corrupted disk. It's suggested that you run CHKDSK.

  • Hello David,

    Yes I have run through DISM, SFC and all drivers are up to date.

    I have tested wtih SMB2 & 3 disabled.

    Sadly the only way this seemed to get cured was with a format and full rebuild.
    In place upgrade or repair wouldn't resolve the issue with the system talking to the system drivers, it did however reduce the frequency of the problems but wasn't a cure.

    Manually replaced the system files listed in the dumps for known working ones and no change detected on the machine.

  • Hi,

    Have you tried to use SMB 1.0 to access network files?

    Please update device drivers to the latest.

    Also, use “sfc /scannow” to check/repair system files.

    Best Regards,

    You could try performing an in-place upgrade, which is re-installing Windows on itself: this will restore all the operating system files while preserving the installed applications and the data.
    Insert the Windows 10 installation disc and reboot your system from that disc: choose the option to do an upgrade installation when prompted and wait for the Windows setup program to complete its job.

    Bye.

  • Hello Luigi,

    I have already done this using the same version and the updated version of Windows this made no change on the isue aside from increasing the time between the system crash.

    I will mark the answer as the format and rebuild but this resource may help anyone else encountering this on Windows 10 to save a few hours of time.

    Kind regards,

    Jamie

  • Please comment into the thread whether you need help troubleshooting or whether you are planning clean install.

    If you need help troubleshooting logs can be scanned and files can be debugged.

  • SMB dialect 3 or 3.1.1 in use on network shares.

    Problem appeared to reduce in frequency for 1 user following full rebuild of system.

    2 more staff impacted who have had the issue refuse to reduce following upgrade/rebuild/downgrade of OS.
    Changed systems between the two staff members and problem stopped, replaced user accounts and put them back onto the original computer problem came back right away.

    This needs to be looked at if you search mrxsmb20.sys on these forums there are over 22k posts only a hotfix exists for Windows 7 which I don't believe relates to this but it does specify for the longhorn issue under SMB1.
    These shares all use the more modern protocol so I am unsure why it calls longhorn to be used as from what I understand that is used with SMB1.

    Attempted running systems with SMB disabled then re-enabling 2 & 3 performance was horrendous with system interupts using 100% of cpu constantly.

    I have since given each person a new machine as two were brand new machines which rebuildng with various versions of Windows 10 made no change to me this is concerning.

  • I was getting a blue screen stop code "rdr_file_system" "mrxsmb20.sys" on windows 10 when browsing a mapped drive in Windows Explorer. I found this post:

    https://www.neowin.net/forum/topic/1383449-win10-gsod-rdr_file_system-mrxsmbsys/?tab=comments#comment-598460756

    And confirmed that even though the mapped drive was enabled for offline folders and there was nothing in the cache, adding the reg entry and rebooting seems to have fixed it.

    From an elevated powershell (right click the Powershell icon, Run as Administrator):

    Set-ItemProperty 'HKLM:\SYSTEM\CurrentControlSet\Services\CSC\Parameters' -Name "FormatDatabase" -Value "1" -Type DWord
    Then reboot.

  • Hello Ahso-dex,

    I will definitely give this a go as and when we see the issue comes back.
