Yep there was. For anyone else with similar issue...
Establish printer IP (something like: 192.168.0.60) > enter this into your browser to access the Brother web admin panel. Default user and pass = (admin / access) > Click Network Configuration > Node Name. Change this to your desired name and then I had to disconnect ethernet cable from printer and reconnect. On reboot of PC it changed the name under Network.
All the best
