Frankly, if you don't know for certain what's in the config, it's impossible to advise a solution. I don't understand phrases like "does not use NameVirtualHost" - if you want to do name-based VHing, you *must* use NameVirtualHost. This is the very directive that makes NBVHing work and if you don't put it in, it won't. It's not some optional extra syntactic sugar or something... > > Could I force the latest apache on FC3?

This is not such a leap in the dark - I'm sure there are thousands of 2.2 servers running on Linux. > Are all its configs backwardly compatible with 2.0.51? There are several config changes between 1.3 and 2.2 so in general a 1.3 config can't be expected to work immediately on a 2.2 server. I'm not too sure about 2.0, but I suspect there would be some changes required (it all depends on the directives you use - 95% are unchanged but there are always a few that have altered; mostly in mod_auth and mod_proxy...) However, if the underlying config is broken (ie, has no NameVirtualHost directive and tries to do name-based VHing) then upgrading won't help you.
