How to configure NICS for HYPER V machine on Domain Controller ?
Posted on 2011-09-17
We have hosted a hyper v machine in a DC , which is having 4 NICS. Out of 4 , the first NIC is for DC itself i.e. NIC1 with an IP of 192.168.1.10. In advanced settings, adapter binding settings the NIC1 is on top. For Hyper V machine, I have created an external network adapter by selecting NIC 4. The NIC1 and NIC4 ports are physically connected to a 2960switch. Now in the DC’s network adapter shows as total 5 including one virtual switch.
Given a separate IP address from different subnet for NIC4 i.e. 192.168.16.20 . Next , removed the tick mark from’ register this connection to DNS suffix’ and disabled NetBIOS over tcpip. The problem is, still our dns record shows both IP for the domain controller i.e. 192.168.1.10 & 192.168.16.20 , thus effecting our total network performance and connectivity. This domain controller is a DHCP server too. Daily our wireless users complaints that , they are unable to connect the network and when I delete the second ip (192.168.16.20) the connection becomes ok.
My question what is the wrong in configuration ? What is the best practice.
