Secondary Domain Controller
All,
I have had some issues with three remote offices and the main DC. Here is the previous thread number: 23581531. Basically, there are three offices and each are connected with a point-to-point connection. There was one DC in the main office and file servers in each remote office. Everything works great, but the other day, the internet went down in the main office, cutting off communication from the remote offices. The remote offices lost the ability to connect to local resources, getting lots of authentication errors.
It was suggested that I make each file server in the remote offices additional DCs and also make them Global Catalogs so that if the connection went down again, the remote offices would not lose connectivity. Well, I made both respective file servers backup DCs and Global Catalog servers and I still have the same exact problem. I have DHCP giving the workstations in each remote office the local server as the DNS server.
Is there something I missed or is there another way to fix this situation?

I had not waited 24 hours when I first tried it so I will revisit that and see if it makes a difference. What would be the proper way to handle addressing at each office?
Thanks

I can understand the Internet connection going down, because you may have DNS set to forward all queries to DNS servers in the main office. Provided you are using Active Directory-integrated DNS (http://support.microsoft.com/kb/198437) and you have DNS installed on all the local servers (http://support.microsoft.com/kb/814591), forwarders should be set to forward requests to the ISP's DNS servers (at every site) (http://technet2.microsoft.com/WindowsServer/en/Library/ee992253-235e-4fd4-b4da-7e57e70ad3821033.mspx).
