I have got Virtual Server 2005 R2 up and running fine on the box using just one LAN card.
When I add in a second LAN card I can configure the virtual machine to use that card by creating another virtual network. All OK so far.
The problem I have is how do I stop the HOST OS from using that second LAN card? If I disable it in the HOST OS then it cannot be used in the virtual machine. If I do not disable it the the HOST machine acquires a second IP address. That screws up my WINS - the HOST machine is a WINS server. The WINS server sees the second IP address and takes it on (you can see that in the WINS manager). Because all the workstations have the HOST's first IP as their WINS address, they lose the ability to browse the network properly.
Ideally I want the virtual server ONLY to use the second LAN card, the HOST machine shouldn't use it.
