Windows 2008 Server R2 crash at classpnp.sys, Stop: C000021a {Fatal System Error} RRS feed

  • Question

  • Hi, I tried severals recovery methods but I still have crashing the server. I already tried safe mode and all the variants.

    I also try starting with WinRE CD installation, I could check the partitions with diskpart and all is ok, I try to use StartRep.exe but the program could not repair automatically, and shows as a root cause that Unspecified changes to system configuration have caused the problem.

    I tried a sfc /scannow offline bootdir and windir unsuccessfully.. just show the next message:

    Windows Resource Protection could not perform the requested operations

    Help! please

  • You are getting a error "Windows Resource Protection could not perform the requested operations" because of you are trying to modify temporary file of rescue mode.

    If you run command then run it on C:\ drive or D:\ Drive.

    X:\ Drive is a temporary drive created by Rescue mode.

    If you want to delete any file which cause issue then look at this tutorial:
