PC adding to domain

I have build up a parlell exchange server and i am restoring exchange backup from live running exchange to parlell exchange server . My plan is to replace live exchange server with parlell exchange server if in case live running server fails. My problem is adding compuer object to parlelll exchange server . We have 200 users in network. This parlell exchange server i have not connected to existing network . I am trying to add PC with same name and IP of exisiting PC names , but i am using same PC to do this job. Problem what i am facing is that the last name addedd only exists in domain. I want to know whether MAC address of NIC is being checked while adding to domain. Also , whether this is creating problem.

This is not going to work.
You CANNOT have two machines on the same domain with the same name and same IP. AD doesn't do anything with the MAC address - but it does use uniquely generated security IDs (SIDs) and no two systems (or users) can have the same SID.

If you want exchange redundancy I suggest you look into two options...
1. Consider Clustering
2. Consider a product like double take or neverfail - two products that will mirror the exchange server to another system and keep it live.

How would a netbios alias allow mailboxes to live on two servers? That's what would be needed... and that cannot be done in a standard exchange config (and I've never heard of it in any other config).
