If you are using name based virtual hosts the global ServerName setting
will never be used.

There are several pieces that all have to tie together.  First you
have to tell apache what addresses/ports to listen on in the global
section.  Then you say that connections accepted on some or all
of these address/port combinations are should also check the
host header for named virtual hosts by using one or more
NameVirtualHost entries.  Then you tie a specific virtual host
to the address/port combination(s) permitted for it by specifying
the same address/port in the VirtualHost tag as you did in the
corresponding NameVirtualHost entry.  Then you specify the names
accepted for that VirtualHost entry in the enclosed ServerName and
ServerAlias tags.  If none of the names match, you get the first
VirtualHost entry for the address(s)/port(s) that match the
inbound connection, or if none of the NameVirtualHost entries
cover that address/port you get either a virtualhost specifically
bound to that combination, or if none exists, you get the global
site.
