1) Are the DCs all in the same domain? Obviously you need a DC in the same domain as the clients. 2) Are the DCs in Site B and C GCs? You need a GC to log on. 3) Can the Site A clients resolve DNS names if both DCs in Site A are down? Clients locate DCs through DNS; no DNS, no logon. 4) Are there firewalls between Site A and B/C? Firewalls require some configuration to allow authentication and replication traffic.
If none of the above, then most likely the SRV records for the Site B and C DCs aren't updated properly in DNS. DCDIAG can help sort that out. -gil -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matt Brown Sent: Monday, March 28, 2005 1:55 PM To: [email protected] 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?
