Hi,
This is a very strange error. Hope that someone can give us a clue what is causing it.
We have a DELPHI 7 program that have been running for several years without problems.
Now on certain new machines we get a "First chance exception" when calling a SOAP function on an J-boss server.
The program works fine on older machines but not on some newer.
Traces have been made, both with Depends and Procmon on machines that are working and not. On the not working machines the trace just stop after the exception.
The running production environment are Windows Server 2003 SP1. The servers have exactly the same plattform versions.
We have written test programs in DELPHI 7 (same environment as production) and also in .NET calling the same SOAP function. .NET test program works but not DELPHI 7.
Extraction from both traces are shown below for DELPHI test program.
DEPENDS TRACE.

We can also mention that the machines are created from the same image as the old ones.
It must have something to do with the DELPHI environment versus the machine configuration though the .NET test progam works.

We are looking forward to some theories/solutions that can help us forward.

Everything else are working on the mahcines. It is just the SOAP calls to the J-BOSS server that fails ...
