IW XIV ISAPI - 500 internal error. Ok with D7 & Version 5 Any ideas?

Tried out Intraweb using Delphi 7 Pro with original bundled Intraweb 5.0. The ISAPI application runs fine on IIS on a Win2012 server. This worked easily enough so spent a few pennies and upgraded a Delphi Professional 2010 to Intraweb XIV Ultimate and built a similar application page again as ISAPI. This works well everywhere that I have accessed it on the web except for the customer when viewed within his large well protected corporate network where users simply get Internal Server Error 500 . The Delphi 7 / IW 5 version works fine though for them. This is with both Chrome and IE (8) in the corporate network.

I note that the IW5 older version shows links in the browser like this IWProjectISAPI_4.dll/EXEC/0/84C1A70368A3394D95BBE440 whereas the newer IW14 are like this : IWProjectISAPI.dll/$/ . This might be clue?

IW14 has so many useful features we don't want to have to run on IW5!

Any ideas on tracking this down and solving it?

Solved - Modified the server Web.config to reveal true error message that showed a security error caused by a change of responding IP detected by the server controller. ServerController. SecurityOption 'SameIP' set to false and now no errors. This should be false as a default according to documentation. Was not an option for earlier IWversions Edited by: bill bulford on Mar 31, 2016 3:21 PM
