Wrong IP address returned by DNS.
Posted on 2004-08-30
Here is what I have.
Windows 2000 DC (DC2) running IIS that hosts three websites.
Three IP addresses (A,B, and C) are assigned to the server's NIC. 3 DNS A records: one for each IP address. IP A is the original IP with B & C added for use as a dedicated IP for two websites. These websites are publically accessible through NAT at the firewall.
There is another DC (DC1) on the domain that provides DNS resolution for the network. All clients are configured to use DC1 as their only DNS server.
Website B & C are password protected wtih NTFS.
When I ping the server name I get IP C back when I want to get IP A. Anytime I try to access website A, I get the password prompt for website C. I have checked DNS and see all the A records for the three IP addresses. I even went as far as to uncheck the box
I created a host header name for website A so it would correctly access the website with sysadmin.blah.com. That piece works fine.
I have been going in circles on this.
Any suggestions on how to control which IP address is returned by DNS? I had deleted out the A records for IP B & C, bu they came back.
