Move to new certifier

Our requests for name changes - move to new certifier have just stopped working. We only get as far as selecting the new certifier using the admin client tools. We get no errors, but nothing happens when we click the OK button. It was working perfectly. We have tried different admin clients, restarted the server but no joy. Any ideas?

Hey,

Its worth checking that no-one has deleted your certlog.nsf from your admin server.

Its also woth checking that you administration server for the names.nsf hasnt been changed to a incorrect server.
