    I've noticed some behaviour that might point to a solution, which of course
    I can't find :-P I looked at the IIS log in
    %windir%\system32\logfiles\ex<date>.log and found that my page was
    requesting the dll representing the UserControl:
    (Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.2;+.NET+CLR+1.1.4322)
    clipped from each log entry)

    2004-07-26 07:55:52 127.0.0.1 GET /ProductIssues/mediaclient.dll - 80 -
    127.0.0.1 200 0 0

    And got 200 - success. However, it then attempted to get the dll from
    everywhere else:

    2004-07-26 07:55:54 127.0.0.1 GET /MediaClient.DLL - 80 - 127.0.0.1 404 0 2
    2004-07-26 07:55:54 127.0.0.1 GET /MediaClient/MediaClient.DLL - 80 -
    127.0.0.1 404 0 3
    2004-07-26 07:55:54 127.0.0.1 GET /bin/MediaClient.DLL - 80 - 127.0.0.1 404
    0 2
    2004-07-26 07:55:54 127.0.0.1 GET /bin/MediaClient/MediaClient.DLL - 80 -
    127.0.0.1 404 0 2
    2004-07-26 07:55:54 127.0.0.1 GET /MediaClient.EXE - 80 - 127.0.0.1 404 0 2
    2004-07-26 07:55:54 127.0.0.1 GET /MediaClient/MediaClient.EXE - 80 -
    127.0.0.1 404 0 3
    2004-07-26 07:55:54 127.0.0.1 GET /bin/MediaClient.EXE - 80 - 127.0.0.1 404
    0 2
    2004-07-26 07:55:54 127.0.0.1 GET /bin/MediaClient/MediaClient.EXE - 80 -
    127.0.0.1 404 0 2

    With 404's on all of those obviously. Does anyone have any idea what could
    cause this sort of behaviour? I tried with an unsigned version of the dll
    though, and it produced the same effect, so perhaps this isn't relevant.
    Interestign behaviour though

    Thanks
