That depends... Have you configured in GPOs or through the registry which records a DC should register?
If your site A your hub location and the other (B and C) the branch offices? Have you configured your hub DCs (site A) to register domain and site records and have you configured your branch office DCs to register only site records and not domain records? If both answers are YES then this could be the problem. Clients first try to contact DCs in their own site and if none of those DCs are available they try to contact DCs in other sites that have registered the domain-wide records. Also make sure the clients can reach other DNS servers and GC servers. The following came from http://www.windowsitpro.com/Articles/ArticleID/40718/40718.html ############### Ideally, when a Windows client can't contact a local (i.e., onsite) DC, it would use site link costs in the AD site topology to determine the next closest site and attempt to contact a DC there. If DCs in that site weren't available, the client would look to the next closest site and try again, looping until it found a DC. Unfortunately, the DC locator process hasn't reached that state yet. In Windows Server 2003 and Win2K, the client requests a list of DCs in its site and domain. If these DCs aren't available, the client requests a list of all DCs in its domain. ############### Jorge -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matt Brown Sent: maandag 28 maart 2005 22:55 To: ActiveDir@mail.activedir.org Subject: [ActiveDir] AD Site Confusion I have 3 sites, site A has 2 DC's and site B & C each have 1 DC. When I take down site A (both DC's), the clients in Site A cannot log in. Shouldn't they be able to log in using site B or C?
