    Thanks for looking into this. I'll put the requested information below:

    They all used to use the similiar configuration files with the exception
    of the IP's placed in the VirtualHost entries until we upgraded the
    Production Web machine to use apache2 and the Min/Max/Start servers
    entries. I'll put the relavent stuff below...Keep in mind that things
    were slow on the production machine before we upgraded it to apache2,
    which is still slow.
