    Sorry, but I think that you need to ask support staff for Crystal Report:
    1. Whether they support running on IIS6
    2. If yes to #1, what configuration is necessary

    If you follow their steps and it does not work, then they need to show there
    is an IIS6 bug for it to be an IIS6 issue. Otherwise, it is simply
    misconfiguration of their own product -- and they are responsible for that.

    IIS6 has no such lockdown that you are imagining. Neither the Crystal Report
    DLL, nor FSO, nor your VB6 DLL are considered "part of IIS6" and given
    special treatment to write to the filesystem - they are all considered COM
    objects. If you configure them all to load in the same application and one
    can write to the filesystem, then they can all write to the filesystem.

    Bottom line: I think you are doing a whole bunch of work that Crystal
    Designer support team is supposed to handle for you, and I do not see an IIS
    issue here at all. Crystal Designer is obligated to make this work for you
    or prove it is an IIS6 bug.

Hello David
Thanks for your reply,
you know what I already asked them and they say use Crystal Report 9 or 10
and I tried both of them but it still just creates the 0KB file and doesnt
go
ahead!
when I use IIS5 everything works fine, David, I am thinking there should be
some way in IIS6 to tell him that please let this DLL export the report
because of tightened security.
I checked all the permission and IWPG_ user all the required permission,
IIS6 is able to write to text file using FSO because it is its own DLL,
while
Crystal Designer Library is not by IIS6 so I am thinkikng more towards
solving it from IIS point of view.
Please let me know how can I use external DLL in IIS6 say for example the
DLL created in VB6.
Regards and many thanks!
