Firstly, FrontPage server extensions are end-of-life and should not be used on a production server.
We will not be able to offer any techincal support for FrontPage.
If you are using frontpage, but are using apache 1.3 compiled with custombuild (instead of customapache), if you see this error:
The requested URL /_vti_bin/_vti_adm/fpadmcgi.exe was not found on this server.
a reported (untested) solution is to use these options in your main httpd.conf:<IfModule mod_frontpage.c>
FrontPageEnable
FrontPageAdminEnable
</IfModule>
