NIC Teaming

[slider1578]

I'm hoping someone can help me out.

 

I have a Windows server with three NIC, 1x on board, 2x on card.  I've teamed the two on the card together in Switch Dependent and LACP and also aggregated the ports on the router.  I want the server to use this team for essentially everything, saving the other port for RDP/management.

 

As of now the server flip-flops between whichever NIC is wants (teamed or the single). 

 

Any help or tips is appreciated.

Well as long as you connect to RDP to the IP of the non-teamed NIC, it shouldn't be using the bonded connection. If it is, you have a bigger problem.

are you connecting to the server using a DNS name? if so could it be possible that DNS is resolving to the IP address of the wrong port (team) instead of your dedicated NIC?

If this is the case then I would do a a couple nslookups (nslookup) on your server's name and see what IP address DNS is resolving to.

I think the problem is that all the connections, while having 2 IP addresses still use the same NETBIOS/DNS name, that's also probably why you are seeing the flipping behavior.

 

If you have your own local DNS server, set hard entries for both cards and give them different names like serverx.my.lan and serverx-man.my.lan. That should solve your problem!

 

If you don't have a DNS servers, set it in all the host files on your network.

I don't have a DNS server, but I'll work with the host files this evening and report back, thanks.
