I have FP2002 and downloaded the 2002 Server Extensions at
http://www.rtr.com/. I was only able to get it working after reading one of the walk throughs. If you do a search on their site there are some walk throughs depending on the OS and extensions you are using.
I found your post in doing a search to see how others are handling getting rid of server extensions since MS announced "End of Life" for FPSE by 2005/2006.
I am pretty much fed up anyway with having to go through re-installation every time I update for an apache security fix.
