SUMMARY
=======

This article provides information about profiling an ISAPI DLL. This information
is not available in Microsoft Source Profiler documentation.

MORE INFORMATION
================

Use the following steps to profile an ISAPI DLL:

1. Build your DLL. Enable profiling and generation of a map file on the linker
   options.

2. Run this command on your ISAPI DLL:

   prep /om /ft <yourDLL>.dll

3. This generates a file called <yourDLL>._ll. Rename your original DLL to
   something else and then rename the ._ll file to <yourDLL>.dll.

4. Copy this profiling version of your ISAPI dll and profile.dll to the
   directory where they will be run on your IIS server.

5. Copy the following files from the \Microsoft Visual Studio\VC98\Bin directory
   to where they will be run on your IIS server:

   Profile.EXE, Profile.DLL, Profile.Ini.

6. Set the __ProfileBPI and __ProfilePBO environment variables as per the
   instructions in the Knowledge Base article:

   Q117681 Profiling Windows NT Services

7. Stop and restart IIS (to ensure that the environment variables are valid for
   Inetinfo.exe while it is running) and then run whatever processes you are
   going to use to exercise the code in your ISAPI DLL.

   NOTE: To stop IIS 4.0, issue this command: net stop iisadmin /y To start Web
   Publishing Service again, use: net start w3svc.

8. Stop IIS and run these commands in the directory where the PBI and PBO files
   are located:

   prep /m <yourDLL>
   plist <yourDLL>

   NOTE: Do not add the .DLL extension onto these last two commands. Errors are
   generated if .DLL extension is added.
