We've recently been trying to transfer two domains from the registrar
TierraNet, aka DomainDiscover.
The transfers were denied by DomainDiscover, although the registrant said
he did not receive any sort of communication from them.
Upon investigation, it turns out that DomainDiscover has a default lock
on all domains. To enable a transfer, the registrant first must log into
the DomainDiscover control panel, click the "Switch away from
DomainDiscover" link, and type an e-mail message detailing the name of
the new registrar and "the reason for switching away from DomainDiscover"
(!).
After some period of time, they will remove the lock and you can then
transfer it.
As far as I'm concerned, this form of default NACK is even worse than
what NSI is doing, because upon receiving a transfer request,
DomainDiscover apparently doesn't even send a notice to the customer
saying that they're going to be rejecting the transfer or indicating what
the customer needs to do to make it happen.
