It looks like the host in your disklist doesn't match what the IP resolves to, 
but only
because your DNS resolution isn't set up for unqualified hostnames.  See below.

Using 'localhost' as a DLE will bite you someday, see the the 'Top 10' list for
reasons: <http://www.amanda.org/docs/topten.html#id2554763>

They don't match on the server (they might not match on the client, either, but 
I think
the server is where that error is generated.  You probably need:
domain  OurDomain.com
in the resolv.conf (or equivilent) on your amanda server so that your server 
knows
to append your domain name to the hostname  before doing the lookup.
A workaround would be to use the FQDN in your disklist, but it's best to fix 
the actual
problem.
