RDR_FILE_SYSTEM mrxsmb20.sys error after feature upgrade Windows 10 2004 10.0.19041.1 RRS feed

  • Question

  • Hi,

    I am experiencing the same problems as @CalvaryIT as stated in this post.Read here It was after we upgraded 2 machines' feature update to Windows 10 2004 and both of the machines have this issue. The others have yet to experience this issue as they are still on 1909.

    I have tried formatting database of Offline Files (via registry) as suggested in a thread (dated back to 2017) but that didn't work as errors still appeared after. Our environment makes use of Offline Files and Folder Redirect (My Documents and Downloads folder) for users that are out of the office so I don't think I can disable Offline Files. I am thinking of rolling back to 1909 but would like some feedback on this issue.

    My minidump file is attached here. 

    RDR_FILE_SYSTEM (27)
        If you see RxExceptionFilter on the stack then the 2nd and 3rd parameters are the
        exception record and context record. Do a .cxr on the 3rd parameter and then kb to
        obtain a more informative stack trace.
        The high 16 bits of the first parameter is the RDBSS bugcheck code, which is defined
        as follows:
         RDBSS_BUG_CHECK_CACHESUP  = 0xca550000,
         RDBSS_BUG_CHECK_CLEANUP   = 0xc1ee0000,
         RDBSS_BUG_CHECK_CLOSE     = 0xc10e0000,
         RDBSS_BUG_CHECK_NTEXCEPT  = 0xbaad0000,
    Arguments:
    Arg1: 00000000baad0073
    Arg2: fffff60c794defc8
    Arg3: fffff60c794de800
