Sites - Public / Global adress.

Hi, im having a real nightmare here !

I have an front end exchange server configured inside our DMZ,
with a public ip address assigned to one of its NICs.

I have entered both network/mask into sites MMC snap-in, and all seems
fine as rest of out AD implementain works fine. but the front end server
doesnt
seem to think its in the correct site although its subnet as been placed
into our UK site.

the netlogon.log file has the "NO_CLIENT_SITE" error next to this machine..

Is it not possible to use Public IP address/mask to define a site ?

We will in the near future be using few public ip's for our support personal
here, and we have the same issue with the few i have tested... being that
they are not sure what site they are in and try and authenticate from random
DC's.

Is there anyway we can force all "No_CLIENT_SITE" clients to default to a
certian site or force just a few machines to always authenticate using a
certain DC.

Please help, this has been driving me crazy all day !

Many thanks,

Mike

Sites are used to manage replication and authentication within the forest
over slow links. The domain members and the domain controllers need to be on
the same network/subnet in the site for it to work properly in that domain
members tries to authenticate first to domain controller in the site and
this normally would be a "private" network address. Domain members determine
their site by their network address. I am not sure exactly what you are
trying to do but it would be highly unusual to create a site with public
network address. Another thing to check is that for computers with more than
one network adapter, always place the local lan network adapter used for AD
domain traffic at the top of the priority list in network
connections/advanced/advanced settings. --- Steve
