I'm not an expert, but I would be inclined to ask what you mean by "have
re-created the Oracle Service using the
oradmin command".  What happened to the original service?  Is it still
there?  Is it running?  You're not going to get the instance to initialize
if that service isn't running.  Have you rebooted the system?  Does the
service start at boot?

My philosophy is to look for the simple problems first.  You can always go
on to look for more complex ones later.
