Yeah I know what a hosts file is. So the hosts file would supply the
address for only the domain logon, i.e. the PDC... and Internet DNS would
go through the Primary or Secondary DNS Server defined in the IP
Properties? Are you sure about this?
If your hosts file exists, it will always be checked first before any
DNS queries are sent out. Any machine that is sitting in the hosts
file will be resolved there, anything that isn't in the hosts file
results in a DNS query.
The only potential problem here is that you're talking about a PDC
rather than a plain old IP server. Microsoft has all sorts of crap
for it's own networking stuff and I can never keep track of what
protocol is used for what connection. I'm pretty certain that they
now do all this stuff with straight TCP/IP and no longer worry about
any of that old NetBIOS or WINS resolution, but you might need to look
into that in case there's some old backwards compatibility cruft left
over from days gone by.
The problem with M$ is that they have half-assed layered their own legacy
stuff on top of the IETF IP rules. For a while, a few years ago, they kept
trying to get IETF to accept their way of doing things and kept getting
laughed out of the meetings.
Hehe, yup, getting back to what I just wrote above about all the old
legacy cruft that you might run into! :>
