Added defaulting of domain/workgroup name to 'WORKGROUP' when the domain cannot

be resolved via network broadcast. Also outputs a message to indicate the domain
was defaulted and possible causes (firewall settings/broadcast mask).
Added hint message to check the broadcast mask when the host announcer fails
with an IOException.
