Activate Server 2012 Server Core Eval


I am setting up a study lab on my  Windows 7 workstation.  I have VMware Workstation installed and have setup an evaluation version of Server 2012 R2 as a VM.  So far so good.  It is activated by using NAT and I have 180 days to play with it.  Well, I also need an installation of Server 2012 R2 Server Core.  I took the same ISO file and installed a copy of Server 2012 R2 Server Core as an additional VM.  The problem I am having is that it will not activate.  I am in the midst of the 10 day countdown.  I have the same NAT setup as the other VM, but can't seem to get it to activate.  I am getting the necessary IP configurations.  I can ping  Any ideas?

Are you using the same Product Key ?

Even if the product is not activated it will still run.

Well, I used the same ISO file for the server core installation as I did for the GUI install?  It is an evaluation version.  I don't have a product key.  Yes, it is running, but you only have 10 days to activate it to get the 180 days.  I only have 9 days left now.

can you switch the networking to BRIDGED just for test and Activation ?

I suppose I would have to statically assign all of the adapter settings for that to work?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
It depends if you have DHCP on your LAN, otherwise yes, it would need an IP Address.

Okay, so I changed it to Bridged and assigned all of the adapter settings.  She still won't activate.  Do you think it has anything to do with the fact I used the same ISO for the install?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
It's possible, or you have lack of networking and internet.

When I was NAT'd, I could see the internet just fine.  Now it seems I can't with bridging in place?  Like I said, I was able to activate the Server 2012 GUI install just fine with NAT in place.  Maybe I have it setup wrong?  Seems pretty straight forward though.
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
When you are using a NATed networking configuration, it connects an uses the Internet, via the PC's Internet Network Interface and IP Address. (and internally VMware Workstation DHCP server gives your VM an IP Address)

So NAT IP Address > Physical IP Address in host > Internet.

When you select BRIDGED, this passes the traffic through the Physical IP Address in the host....

but this means that it will expect a DHCP server on your network toy get an IP Address.

So on your LAN, how do devices get an IP Address?

Where does the host get it's IP Address ?

What is the IP Address in the 2012 Server ?

Either way NAT or Bridged should both have access to the internet, usually NAT is more likely to fail getting to the internet, compared to BRIDGED (but you do need to have IP Addresses allocated to computers, manually or via DHCP)
