Bizarre Web Service Error

    The following text is the result of calling a web service
    (FN003) locally using the test page. During its
    processing, the web service calls a second web service
    (FN006) on the same box.

    It appears to be searching for a missing temporary dll,
    though I have no idea why. The name of the dll changes
    from one call to the next. Any help would be greatly
    appreciated.

  2. there is an error in the XML serializer than can sometimes lead to this
    symptom.
    In the case where you have particularly complex object graph, involving
    jagged arrays without a specific attriubute applied to them, the Xml
    Serializer will choke. If you apply the attribute, the serializer will be
    fine.

    See http://tinyurl.com/rqwl

    to troubleshoot this, I would recommend:
    1. examine your datatypes for a jagged or 2-d array
    2. simplify the data types being sent and received to simple types
    3. add in complexity, until you see the error
    4. apply the attribute and see if this resolves your issue

    There can be other causes of this mystifying message, but this is the one I
    have seen most commonly.
