This is a test environment done for client on one server and client . We are having Windows 2003 Server acting as Domain Controller with static IP as 192.168.1.1 and domain name is for Eg abc.com . DNS entry on the server points to 127.0.0.1. Abc is the real domain name of the client on the web. DNS shows A record for the client mapped to 192.168.1.2. Hostname of server is source.
There is ONLY one client running Windows 2012 Std R2 with IP as 192.168.1.2. First DNS entry of the client points to 192.168.1.1. Hostname is target.Firewall is off in Server and Client.
On Server if I ping by
- abc.com - ping response comes from 192.168.1.1, which is correct
- client ip- Request timed out
- client hostname or FQDN- It shows pinging target.abc.com (192.168.1.2) with 32 bytes of data and then comes request timed out
Nslookup resloves everything on the server.
On the client. If I ping by
- abc.com- pinging target.abc.com (Real IP) with 32 bytes of data
Reply from *.*.*.*: bytes=32 time=240ms TTL=43REAL IP OF Domain Name
- Server IP- Reply from 192.168.1.1. Destination host unreachable
- Server hostname or FQDN - Ping request couldnot find the host source.abc.com.Please check the name and try again.
C:\Users\administrator.abc>nslookup
DNS request timed out.
timeout was 2 seconds.
Default Server: UnKnown

*** Request to UnKnown timed-out
Both Server and client are not pinging each other. Because of Application concerns I cannot remove the client from domain now and would like to do it as last resort.
