Just upgraded to Win 7 Ultimate, IIS 7.5. I am having trouble configuring IIS to execute a particular file (webinn.dll) It has been working fine under win XP and IIS 6. Other test files work fine. (validate.dll) and webinn.exe works. webinn.exe is an exact copy of webinn.dll (just compiled differently) The following links may help. https:/secure.cowhollowmotorinn.com/reservations/webinn.exe (works), https:/secure.cowhollowmotorinn.com/reservations/webinn.dll (internal server error), https:/secure.cowhollowmotorinn.com/reservations/validate.dll. (works, just a test) I did not write the files but need to know what is causing the error, IIS or the file webinn.dll? Thank you, Chuck

I have a feeling this is related to setting up an ISAPI filter, but I would ask here, http://forums.iis.net/ -- Mike Burr
