I have noticed that my clients are authenticating against domain controllers that are not local to them. I have checked the site and services, the settings are correct. I have been doing some research and located the option to setup the DC Locator Server http://searchwinit.techtarget.com/tip/0,289483,sid1_gci1283750,00.html
) . If this option is configured, will it force the computers to authenticate to the subnets that are on that network vs. ones that are not? Also, if forced, if those controllers are down will it authenticate to the local computer or search for remotes listed in DNS?
