Suspected Hacker

While I was reviewing the security event logs I noticed that there were
multiple attempts to log in remotely to the server via an outside ip
addresses.  These ips have changed and the ip traces I have done told me that
the location is all over the place.  Czech Republic, Virginia, LA are just
some of the locations traced.

The account names that are attempting to log in are administrator, terminal,
manager, and several more commonly used account names.  Most of which are not
used in my network.

It seems to me that these are attempts at hacking.  If it is then what steps
should I take to protect my network?

All of them that that apply!

All of them that that apply! Firewall, security updates, make sure all your
passwords are not obvious. If you are not in a domain then get in one and
make sure that nobody outside the domain can connect or join (there are some
IPSec and other options). If it is web server use tools to prevent cross-site
scripting. If you host anything that connects to SQL make sure you cannot get
SQL injection. There are general solutions like a firewall, but you should
do some threat modeling based on your attack surface, as they might say in
the jargon, and then apply the appropriate solutions.

As other noted...  FireWall !

You platform is exposed to the Internet.  You need to put a barrier between you
computer(s) and the internet.  A simple NAT Router or a NAT Router with a Full FireWall
Implemtation will go a long way in mitigating such threats.

Got a computer at home?
it is probably not 'in a domain'.

Have a computer with Windows XP Home Edition?  Windows Vista Home ____?
it is *not* 'in a domain'.

Domains - in the sense of this conversation - are normal in business
environments - allowing management of resources centrally and more readily.
