Could not load file or assembly after IISReset RRS feed

  • Question

  • Hi,

    I have web site running well until recently all of sudden it returns the following error

    "Could not load file or assembly 'xxx' or one of its dependencies.
    Either a required impersonation level was not provided, or the provided impersonation level is invalid.

    The assembly is not specific to a assembly name, one day is "xxx", while another day could be "yyy"

    The error ONLY occurrs after demployment with IISReset or application pool recylce, and its intermittent.

    The web website impersonation is set to True, and hosts some WCF services.  

    Does anyone encounter similar problem before, any suggestion is appreciated.
