hello expert,

How to stop a client from going across a WAN to find a active Domain controller.

I have a windows 2003 active directory domain with 11 sites. (different subnets).

On several occasion clients attempted to crossing subnets to find a nearby D.C when the D.C

within their respective site was up and running.

How can i restrict client(s) to local subnet and not to allow them allowing crossing sites,

I prefer if the a client cannot authenticate in their respective subnet just deny connection

instead of crossing subnets.

Regards
Jomo

Yo need to go into Active Directory Sites and Services
First Define your subnets
Then set-up your sites in AD sites and service and associate each site with one or more subnets
Job Done

Clients will then use a DC in their own site in preference to another DC.

hello KCTS,

>>Then set-up your sites in AD sites and service and associate each site with one or more subnets

I have all the above in place--- but the some clients when their respective

D.C is down temporary will attempt to cross sites to finds a functioning d.c

in a neighboring site.

I would like to prevent this from happen the bandwidth between sites is

only 64kbps.

What i would like is if the d.c within the client's site is not available just

do not allow clients to log in i do not want log on traffic across the WAN.

thanks

alternatively, you could set up an access list on the WAN router to avoid all AD traffic.

That is the default - if the DC on their own site is not available then the clients will attempt to locate another DC. You can block the traffic as tonux suggests but then users at the remote site will not be able to log on - though cached credentials would work.
