Exchange 2000 Enterprise installation on single server

What do you mean expand it to multiple servers later?
Do you mean install more servers in the organzation later? Use the same CD for multiple servers?

Yes, more servers later and with the same cd.

What kind of agreement do you have with Microsoft? If your question is can you add another server to the administrative group later on, then sure, of course.
 If your question is can you use the same CD for multiple servers...it would depend on the agreement you have with Microsoft. I believe technically you are supposed to have a CD and agreement for each server unless otherwise agreed with by Microsoft,  if not, i think that comes close to pirating because you can use the same CD for multiple servers....

If it is a legal issue you are concerned about with using the same CD for multiple servers,..i would contact Microsoft customer service and speak with a sales rep.

If i am way off, then please help me understand where i am missing....

Hope this is helping!

We are getting close. I am noit interested in stealing any sw - I am trying to decide whether to purchase Exchange 2000 vanilla and install it now and upgrade later to enterprise or to order enterprise now even tho it will be used as a normal non-enterprise install right now. If E2000 enterprise installation is going to take a lot longer than E2000 non-enterprise then I will prob. opt for E2000 non-ent because I do not know how long it will be until I need E2000 Enter. features.
So I guess the real question is: how much more difficult is it to install E2000 enterprise as compared to E2000 non-enterprise?
Thanks.

that is what i needed to know. Thanks.
