JDK/Apache/IIS - ISAPI Filter problem

Hello, and thanks in advance-

My setup:
XP Pro (using the IIS that installs with it)
Apache (Jakarta-Tomcat 4.0.1
JDK 1.3.1_02

I am trying to get the ISAPI Redirect to work. I have been following this tutorial http://www.verysimple.com/scripts/support_tc_iis.html, and Apache seems to be starting, and everything seems great until I get to these steps, and do what it says:

--
In the IIS Management Console right-click on your machine name (not the root web) and select properties. Click the Edit button next to the "Master Properties" for the WWW Service. Select the "ISAPI Filters" tab and click "Add" Name the filter "jakarta" and for the executable, browse to C:\Tomcat\bin\isapi_redirect.dll file.
Now go to the control panel, select Services and restart the IIS Admin service (make sure Word Wide Web Publishing Service restarts as well). After you have restarted, go back to the ISAPI filters screen and make sure that the jakarta filter has a green arrow next to it. If it does, then everything is working.

I dont get a green arrow. It is a red arrow. Somethings not working right. Any ideas?

Thanks so much!
