Here is the response through the support team:
Hello,
Sorry but there is no Error log for IIS, there is something in moodle application
which is causing php pages not to work with in moodle, however info.php page which is in moodle directory works.
http://www.kcalaman.com/moodle/info.php
PHP logs for the application would be more informative in this case.
Please feel free to contact us for further assistance.
With Regards,

Which incidently is the same spinning response i had gotten a few other times LOL.
Here is what I sent back:
honestly I am insulted by this continued response. There certainly is an error log for a web server it's ridiculous to say there isn't lol.
My application has it's own error handling but when the errors were thrown IIS intercepted them as it's own errors and threw the 404 error pages from the web server. This incidentally is why the detailed messages were not being returned because the error information was actually in the application itself! So I had to change a configuration parameter in web.config to override this behavior:
<system.webServer>
<httpErrors existingResponse="PassThrough" />
</system.webServer>
I do apologize for my persistence in this matter I truly do and I also appreciate your time and efforts spent trying to help. I am a very busy person as you all are I am sure and I have been stuck for a few weeks on these problems. I haven't been this frustrated since I was really clueless I can say that...but it all comes down to troubleshooting and following the process so you don't spin your wheels. And when you take a critical informational component out of the troubleshooting loop you are really in trouble! It's all about finding actual problems and not putting out fires and we need the proper diagnostics to find the actual problems that we need to solve.
Now I got it working and i can see if there is a way I can figure out some performance problems next. I really think some of this issue comes down to session handling and caching but we shall see. I think I will need to do some analysis of queries in mysql ... I know I am MCDBA and I would certainly be tracing some queries in MSSQL but the diagnostic tools do not seem to be available so I am not sure how it's to be done but we shall see.
