Which modules and extensions do you have enabled?
Do you have any zend_extension's installed?

Hi,
Can you help me get the debug information as per your requirement?
Steps done by me.
1] Installed the VS (Also VS.NET 2003)
2] Initiated request to php page.
3] waited long time, but no reply.
4] Opened Tasklist, Right clicked "php.exe" and clicked Debug.
5] MSVC opens.
6] Problem is the debug code is not getting attached to the php.exe.
I'm getting "'D:\php\php.exe' does not contain debugging information."
I'm stuck here.
==========================================
I've few screenshots, how can I send them to you?
Screenshots shows message stating "The process appears to be deadlocked
(or is not running any user-mode code). All threads have been stopped."
Steps to regenerate.
1] Start VS.NET 2003
2] Request the php page on IIS.
3] Attach php.exe for debugging in VS.NET
4] click on Break button.
==========================================
Below is the copy of call stack taken using VS.NET.

I switched to using php5isapi.dll. (I reinstalled without 'CLI
Executable' option.)
It works fine only for phpinfo(); Running the application gave one more
issue.
==============================================
Out of process application '/LM/W3SVC/1/Root/drupal' terminated
unexpectedly.
==============================================
Every request gives Internal Server 500 error and then on second try it
returns resulted page or empty output.
Thanks Help is needed urgently.
