Server 2008 | The IP address already assigned to another adapter

I’d just done a transfer of one VMware image to another server but the NIC drivers didn’t seem to transfer over correctly. Wasn’t an issue, just added a new virtual adapter but when I tried to add the previously used IP address I got the following message:
Microsoft TCP/IP The IP address 10.77.77.7 you have entered for this network adapter is already assigned to another 'NIC1'. 'NIC1' is hidden from the network and Dial-up Connections folder because it is not physically in the computer or is a legacy adapter that is not working. If the same address is assigned to both adapters and they become active, only one of them will use this address. This may result in incorrect system configuration. Do you want to enter a different IP address for this adapter in the list of IP addresses in the advanced dialog box?
Just to note, this is not specifically a VMware error either. I have come across this before in a genuine installation.

In my eyes there is a design flaw here but I guess this is something we all should be aware of and most of all think twice about how we are protecting our data. So let’s start with how this came about. This all began when I noticed that a file in Google Chrome browser could be transferred from one machine to the next and leave you logged in with whatever site they were using at the time for example; you’re sat in the living room with your girlfriend and of course you know the admin password to her laptop, you’ve fixed it a few times for her before. You go in remotely at ‘c$’, see the file you need, copy and paste then boom you’re on her Facebook account logged as her chatting to her friends impersonating her. The process is known as cookie stealing or session hijacking.
