Server AD, 2 karty sieciowe w różnych podsieciach LAN, iSCSI. Server DNS zwracał ip ze złej podsieci. Np. Będąc w podsieci LAN zwracał ip servera z podsieci iSCSI


To avoid this problem perform the following 3 steps (It is important that you follow all the steps to avoid the issue). 
1. Under Network Connections Properties: 
On the Unwanted NIC TCP/IP Properties -> Advanced -> DNS – > Uncheck “Register this connections Address in DNS” 

2. Open the DNS server console:  highlight the server on the left pane Action-> Properties and on the “Interfaces” tab select “listen on only the following IP addresses”. Remove unwanted IP address from the list

3. On the Zone properties, select Name server tab. Along with FQDN of the DC, you will see the IP address associated with the DC. Remove unwanted IP address if it is listed.

 After performing this delete the existing unwanted Host A record of the DC.
