Specs: Windows 2003
Hello,
I have problem on my network. I´ve 2 domain controllers in 2 sites, I have no problem with DNS or Replication services between servers. But, if I turn off 1st DC in 1st site, clients cannot login to domain in this site, Domain is unavaible, but 2nd DC in 2nd site is working properly. Why clients cannot login to 2nd DC? All servers are Win 2003 R2 32bit
Thanks for reply

But, if I turn off 1st DC in 1st site, clients cannot login to domain in this site,

This is to be expected since the clients at that site will authenticate to that DC. This is why it's recommended you create a second, redundant DC in every location. That way if the one dies, users can still login to the domain and work.

but 2nd DC in 2nd site is working properly. Why clients cannot login to 2nd DC? All servers are Win 2003 R2 32bit

Well, mainly because it's not a redundant DC. Also, it's because it's in a different physical location and a separate logical site within AD.

I don't know that you could make it redundant and have users in site A authenticate to the DC in site B. If there is a way to do this, hopefully someone else who knows how will respond and explain how. But I suspect you can't and will have to bring up a second DC in site A and make it redundant.

The clients should be able to authenicate to the domain but apparently they can't find the other server.

Please post an ipconfig /all from a workstation for review from each site,

I've been away from administering an AD domain too long. I'm glad you jumped in on this wanderer

Could this be a misconfiguration of the site in AD?

I have idea, some workaround, but I´m afraid, that it will be worse. May be, it can help, that I will put second server to first site and delete 2nd site. But if I´m thinking about that, it seems to be nonsense.
