From: Charles on 17 Apr 2010 11:37 I'm searching for information about using NLB on a Windows Server 2008 R2 domain controller, but no luck so far. I have a 2-node NLB cluster on Windows Server 2008 R2 servers, and want to add the Doman Controller role to them. I can't find anywhere that this isn't supported, or that I shouldn't do it, but I wonder if anyone here has any experience of doing it or know of reasons why I can or shouldn't do it? TIA Charles
From: RCan on 17 Apr 2010 16:01 Hi Charles, I personally think the AD DS role is not supported to be run on top of NLB. If you want to achieve load balancing and fault tolerance for NIC/switches why you don't use NIC teaming ? Check this out for an example with Intel NICs -> http://support.dell.com/support/edocs/network/9195p/en/Intel_nic_teaming_10.pdf Regards Ramazan "Charles" <blank(a)nowhere.com> wrote in message news:u3dg0Pk3KHA.4416(a)TK2MSFTNGP06.phx.gbl... > I'm searching for information about using NLB on a Windows Server 2008 R2 > domain controller, but no luck so far. > > I have a 2-node NLB cluster on Windows Server 2008 R2 servers, and want to > add the Doman Controller role to them.

From: Charles on 18 Apr 2010 06:35 Hi Ramazan Thanks for the reply. I will check the link, but the reason for the NLB is several-fold. There is a web site sitting behind the virtual cluster IP, as well as several server apps. Ideally, I would have a couple of low-end servers to act as DCs, but I don't have even that luxury, unfortunately. I'm trying to get the DC role off a Windows Server 2003 cluster so I can do an upgrade (I know it shouldn't be there either, but it was the only way at the time).

From: Meinolf Weber [MVP-DS] on 18 Apr 2010 07:30 Hello charles, Even if it is supported i wouldn't cluster a DC.

Hi Meinolf I've seen that article, and I agree that one shouldn't cluster DCs. Unfortunately, I didn't have a real choice when I did it some time ago, but that is what I'm trying to change now. The article, though, refers to putting a Windows Server Cluster onto DCs, whereas in my post I'm talking about putting NLB onto DCs. This is quite a different type of cluster, so that is why I'm asking whether it is ok and/or supported to do it.
