You'll need to update your delegation with the domain tag holder /
registrar
As in who I registered it with, 123-Reg in this case?
Done, done and done again! (Over several days). The updates are getting
through - if I change the name of the other nameserver, and update the
details via the 123-Reg control panel, it's reflected instantly in the
Nominet listing, for example.
But it will not change this one.
