Mike,

We would need a fair bit more information, but I would suggest using 'dig'
instead of nslookup and specify the server you are querying.  If the error
you are getting is name resolution, then probably either something has not
yet propogated or you've mis-configured it.

Does everything still work/not work the same if you remove the 10.0.1.100
machine from the network?

Are you looking to remove DNS facilities from the 1.100 machine?
