Most of your problem will be in the web server's configuration
and not the DNS. If you can lookup the address in the DNS
then the DNS is configured.
Since you want the server to become www.mttconseil.com
rather than web.mttconseil.com I would make web a CNAME
pointing to www.mttconseil.com and have a A record for
www.mttconseil.com. Note when doing this you need to remove
the existing A record for web.mttconseil.com.
e.g.
web CNAME www
www A 207.35.78.3
