when one DNS DC down can't get to internal web sites Brian 4/17/2007 9:32:03 PM Trying to determine what the issue could be. Have a single domain with 2 DC's, one a W2k svr, the other a W2k3 svr. Both are DNS. When the W2k DC server is down for updates/upgrade etc. cannot get to our internal web sites from domain clients. The internal web sites are hosted in the same domain on a 3rd W2k3 svr running IIS6. I'm thinking this has something to do with DNS but I'm just not sure. Both DC's are running DNS and have the correct internal IP addresses/names for the internal web sites. What am I missing or should be looking at here? The W2k DC srvr is the DHCP for the domain. All the servers have static IPs. Thanks

Probably but it is easy to tell: Just try the IP vs. the DNS name and look for a difference. And/or use NSLookup to test the DNS directly. Every client should have BOTH DNS servers listed on the NIC IP properties; and both DNS servers must be able to resolve "the Internet" through some method (e.g., forwarding or actual recursion.) > Both DC's are running DNS and have the correct > internal IP addresses/names for the internal web sites.

Thanks Isolate the problem to DNS or not. http://IP.the.Web.server Or with NSLookup: nslookup www.domain.com IP.Second.DNS.server Test each DNS server individually and make sure the clients have both listed. -- Herb Martin, MCSE, MVP http://www.LearnQuick.Com (phone on web site)
