Network Load Balancing (NLB) Windows 2008

Hello People...

Here is my question regarding NLB, it is fairly straight forward but I am running into some issues with connectivity. This is a first for me trying this to setup a Web Farm using NLB. So here is my situation... I have 2 Nics one is my public side NAT and the other is my Internal, I use both at this time.

I have installed NLB but have not sected it in the network properties, I choose the public nic in the NLB manager and set the dedicated IP as the public nic static IP address lets say (I use this to remote in via RDP) I set the virtual IP lets say I am using unicast, once this is enabled, problem 1: I can no longer use the .11 address to RDP in. Problem 2: When I add the second host I get error that host A or Host B is misconfigured, usually followed by a network error that the IP address is already in use. Am I missing a step in this process?

    The dedicated IP address is always listed first (before the cluster IP address) in the Internet Protocol (TCP/IP) Properties dialog box. This will ensure that responses to connections originating from a host will return to the same host. For more information, see Set up TCP/IP for Network Load Balancing.
