There is "runas".

There is no accountability with the local admin account.  You can
disable the account and use domain credentials, but when the domain
isn't available, you're screwed, so it is a poor decision.

This will be a big pissing contest as we all have our own opinions though...

In regards to changing the Admin account name, why make it easy for the
kiddiots?  It is trivial for any of us to bypass this, right?  But not
everyone is like us...  Sometimes those kiddiots get lucky, when we make
mistakes.

Changing the Administrator name is just another layer in the onion of
your defensive strategy.  It is done in conjunction with all of the
other changes that have been mentioned.  Which IMO are all equally
important.  Some are definitely more severe in regards to their
consequences, but they all carry a piece of the burden.

And I'm not trying to be a smart ass, but does anyone really use
LM-hashes anymore?
