Anilr I am really very thankful to u on your suggestion about the DebugDiag. I install it and run in following way: 1.

I open Debug Diagnostics Tool 1.0 (Start -> All Programs -> IIS Diagnostics (x86) -> Debug Diagnostics Tool)

2. On the Rules tab, click "Add Rule"3. Select "Crash" option and click "Next"4. Select "All IIS Processes+ COM" option and click "Next"5. Under "Advanced Settings", click "Breakpoints"6. Click "Add Breakpoint"7. Select "KERNEL32!ExitProcess" in the "Offset Expression" list.8. Change "Action Type" to "Full User Dump" 9. Click "Add Breakpoint"10. Select "Kernel32!TerminateProcess" in the "Offset Expression" list.11. Change "Action Type" to "Full User Dump"12. Click "Save and Close"13. Click "Next", "Next" and "Finish"14. Ensure the status of Debug Diagnostic tool "Active"15. Wait for the issue to occur.16. analyze it, go to the Debug Diagnostic Tool once again, and click "Advanced Analysis" tab.17. Click "Add Data Files" and browse to the dump file(w3wp__PID__1612__Date__12_03_2007__Time_01_17_52PM__697__Kernel32!ExitProcess.dmp)18. click "Start Analysis"19. It might take some time to analyze dump file(w3wp__PID__1612__Date__12_03_2007__Time_01_17_52PM__697__Kernel32!ExitProcess.dmp).20. when analysis is complete it create a .mht file with following Summary message.

That means your filter is probably crashing - you will need to attach a debugger to the worker process to get to the bottom of this. You can use DebugDiag to easily collect a crash dump etc.

There is no enabling for ISAPI filters (only extensions) - can you post the complete event details as asked for in the blog post thomas pointed to.

thanks thomad

thanks thomad,

I read it complete and found nothing wrong with my dll. there is no depandcy. I read following lines from net and i thing this is main issue:

"IIS 6 is a lot closer to "secure by default," with ISAPI extensions and filters disabled unless you specifically enable them yourself. In addition, most IIS functionality runs within a very low privileged security context; in IIS 5 and earlier versions, security holes in ISAPI extensions or filters could allow malicious code to run as SYSTEM."

Tell me if u know that how can i enable ISAPI filter in IIS 6. by default it is disable.
