MS server licensing

So I'm probably going the VMware route. People are telling me to get ms server 2008 datacenter, b/c you can install it "on one physical server" and "as many times as you want virtually on one server".

So if I'm going VMware, does that mean I can have two physical servers, one with that datacenter license and another with ESX with 8 copies of windows running.

And how do they screw you with eOpen licenses? Last time I got a few for windows 2003, and only activated 2 of 3 of them. But when i went to activate the last one on their site 2 years later, it said "expired, call us and prove you deserve it" basically. What the hell? I thought the point was if you lost a server and wanted to reinstall that OS you could with eOpen. ???!!! And it really irked me because I basically lost a license unless I ever get time to spend 2 hours on the phone with MS, and probably have to go through some month long audit or something ridiculous.

From what you've typed, I've distilled this question:

If I have one copy of Server 2008, how many times can I install it if I have two physical servers (one running VMware ESX)?

The Server 2008 licensing is for one physical machine with XX number of virtual machines -- on the same physical machine.  The XX number is:

SBS 2008: 1 phys + 1 virt
Server 2008 Std: 1 phys + 1 virt
Server 2008 Enterprise: 1 phys + 4 virt
Server 2008 datacenter: 1 phys + unlimited virt

So, the answer is no, you can't install Server 2008 on a second physical server at all...much less an unilimited number of times.

That was my main question, yes thanks.

How does eOpen work though with that expiration? Surely someone else has run into that situation. I'm about to buy 3 copies of 2008 datacenter eOpen because I need one today, and I expect to eventually use all 3 on 3 ESX servers in a few months. Budgetwise it makes sense to get all 3 today. How much trouble is it to move it from the one I use today to the ESX server later?
Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

Don't know.  I'm not on eOpen.

Maybe someone else can jump in with experience.
I think you'd be better off using the Microsoft Open Value as they charge yearly within minimum of 3 years contract and then during the contract we can submit support and can get up/downgrade right :-)

hope this helps.

Actually, after I read the fine print ours is called "Open Value". So now it all is starting to make sense. We can just continue the "support" at the 3 year mark if we want. Good enough.
goood :-) glad to hear that.
