I can get through to
www.lcarsdatabase.net ok, but
lcarsdatabase.net (without
www) seems to be having trouble resolving.
That's something your host needs to sort out, regarding the
www alias of domains hosted on their server.
Re: Domain Locking.
There should be a setting within your domain registration controls that allows you to lock and unlock your domains.
It's meant as a protection against having 3rd parties initiating the transfer out of your domain, though I'm not sure how realistic such a threat is even without domain locking.
I register domains with GoDaddy and I have all my domains locked by default, only unlocking them temporarily when I need to tweak any of the settings for a domain.
Like I say, I'm not sure how real the dangers are without domain locking, but it makes me feel just that little bit more secure and given that I can lock and unlock them with relative ease, there's no real reason not to keep them locked when I'm not tweaking them.
It's not something designed to keep you out or stop you using your domain, just something intended to offer you (and you r domains) an extra level of protection.
