IIS/PWS fails to load isapi_redirect.dll filter

["Hawkins, Keith (Keith)" <kp...@avaya.com>]

I am trying to get the isapi_redirect.dll filter to run under IIS/PWS.

I have quadruple checked all the values that I need to set up according to
the instructions posted on the Tomcat site.  But every time I stop and start
the web service, I get the dreaded  red down arrow.  (The bane of my
existence these days ;-)

I got the filter set up fine on Windows 2000, but I can't get it going on a
machine running with NT4.0 Service Pack 5.

I have a few questions for those who may have gotten this working correctly
on NT.

1)  If a filter fails to load,  where does IIS/PWS log the problem that is
preventing it from loading??

2)  The instructions say to for PWS I need to add a Filter DLLs key to the
registry.  What is not clear
is whether Filter DLLs is a KEY name with a default value of the full path
to isapi_redirect.dll  or
Filter DLLs is a STRING VALUE entry at the W3SVC/Paramaters level with a
value of the full path to the isapi_redirect.dll. Or do I even need to do
this since I was able to set up a filter entry using the management
console??

Any help would be appreciated.

Thanks,
Keith
