see man hostname for the full details of what your system will use.

Usually on RedHat/Fedora/CentOS type systems, host name is set from
/etc/sysconfig/network via the HOSTNAME= line.

If you used command line commands to set hostname, I would check the
man page for the command, remove the host name setting from indicated config
file, set /etc/sysconfig/network HOSTNAME=to_desired_FQDN_here
Reboot system and see if it works.

No telling since you did not specify your network setup type, wifi,
type of dhcp client if dynamic, static,..

Try
cd /etc/sysconfig/network-scripts/
grep -ri wyzantdb1 *
grep -ri wyzant.net *

You could save/run this script and grep it's output for the above names.

grep -r wyzantdb1 /etc
is more efficient
