It's very clear in the KBs I've looked at that MS strongly recommends
against using a Netbios name over 14 characters long. What not clear to me
is how you could actually accomplish it. I'm curious how you created a
longer name, and if it was by using the standard SBS setup, why it wasn't
blocked. (I plan to ask SBS Dev folks that question.)
As for the solution, if this is a brand new server and new domain, you
should definitely reinstall. If it's an existing domain, it may be possible
to preserve the SID history and accounts information by using a domain
rename or ADMT migration, but these are not trivial, and I'm not
recommending it, just saying it might be possible way out for someone of
both technical skill and strong motivations. If you don't understand the
issues, don't pursue this, just reinstall from scratch.
As for the email address and public addresses, this really hasn't anything
to do with the Netbios domain name used internally. You will be able to keep
whatever public domain name you want, it doesn't need to match the internal
LAN domain.
