use of default isapi filters

We are running IIS 5. We are not running asp.net. Can
someone point me to any documentation on what the default
isapi filters do, which ones can be removed and which ones
should not be removed for security issues etc? We have a
client who has asked us to remove all isapi filters from
the web server we are providing for them for "security
reasons".
Thanks

The usual filters that you'll find installed with IIS5:
1. fpexedll.dll -- FrontPage Server Extensions. Should be removable
2. aspnet_filter -- ASP.Net Cookieless session.
3. sspifilt -- implements SSL. If you don't use SSL, you don't need it
4. compfilt -- implements compression. If you don't use it, you can remove
it
5. md5filt -- implements authentication. If you're using
anonymous/Basic/Integrated, you won't need it.

Other products on the server may install their own filters whose
functionality you are relying on. I have no idea what they are, so you will
have to make your own judgement.
