Hi David,

Thank you very much for taking the time to help me out with this. At first,
I also can't believe that IIS can only open 2,500 window handles but when i
ran the application on a different web server, it proved that it is true. The
other web server can open 3 times more windows than IIS can.

I don't think system resource is a problem as well, coz I've tried running
the .dll on normal PC and server but the result is still the same.

By the way, I'm a little confused when it came to this handles issue. When i
checked the Task Manager, the handles counts under the processor counter
doesn't really reflect the windows handles currently being used by the .dll.
I could see it because i have set the .dll to run as out-of-process
(isolated). So, when you said that your ISAPI (.dll) can open more than 100K
handles, did you mean by looking at that particular counter. Did you make any
changes to the metabase or registry?

Thanks again. Your help and advice is greatly appreciated.

Audrey.
