ok, good, you're on the same subnet :-)
Just had to check.

ok, this concerns me...
Normally I'd set the DNS suffix the same as the name server suffix.
I mean, if your name server is "MyDNS.MyDomain.com" the windows box would
normally be "Paul-Vista.MyDomain.com"

There's your problem!
your DNS server is a secndary DNS server in your config.

>> *** NSLOOKUP ***
>>
>> C:\Windows\system32>nslookup
>> Default Server:  dns.hq.svc.zen.net.uk
>> Address:  212.23.3.100

This proves it.
At the > prompt try typeing - server 192.168.0.210
then type in the name of the machine you're trying to resolve.

>> It looks like it only does the lookup on the primary name server.

indeed, why try the secondary if the primary is giving you a reponse?
this is a valid behaviour, even if the response is "sorry I don't know
that name", it's still a valid response.
You need to make your internal DNS server the primary, and get to refer
it's queries out to your ISPs DNS (212.23.3.100).
That way, if your local one knows the answer, it will give it you, if not,
it'll pass the query to the ISP DNS.
