A) You need a very good firewall protecting your network. Don't use personal
firewall software on a server - use a perimeter firewall - a server or an
appliance - that blocks ports.
B) Disable Guest if you haven't done so already
C) Force complex passwords and regular password changes for all users
D) Rename commonly-used accounts such as administrator to something else
E) Run Windows Update to get all relevant critical patches
F) Run good antivirus software on the server and all workstations - ideally
centrally managed stuff.

It's good you have auditing enabled, or you might never have known anything
about this.
