teaming NICs, Virtual Switch/adapter in Windows 2012
Posted on 2013-06-08
I initially created one Hypver-V guest in my windows 2012. But by that time, I just had to make it work asap, so I have been ignoring wrong settings that I have to adjust now.
this server HP DL380 has 4 NICs. I created a team with 3 and left 1 for emergency access.
Ethernet#1, #2, #3 in Team - static IP 10.10.10.25
Ethernet#4 -dynamic (now assigned 10.10.10.205)
Then I created a hyver-v guest. I created virtual switch with 'external' to allow virtual guest to connect to physical network. (screenshots for these settings attached).
Then I assigned static IP to the guest,10.10.10.170
Now the problem occures in DNS. The host server(10.10.10.25) shows NetBT error telling below and when I looked at DNS, Forward Zone has only one entry for the server and reverse zone has two entries;
"A duplicate name has been detected on the TCP network. The IP address of the computer that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state."
DNS Forward Zone:
FS1 - 10.10.10.205
DNS Reverse Zone:
10.10.10.205 - FS
10.10.10.25 - FS
Since 10.10.10.205 on the server is a single NIC connection with DHCP, I don't want traffic to go to that, but it seems like DNS thinks it's the primary connection. Also, I'm not sure the hyper-v guest on the server is even using the teamed connection or the single connection. How do I resolve the error on the server and make sure DNS is properly configured for this environment and what to do make sure all traffic goes through the teamed NICs to take advantage of bandwidth pool?
