Multiple DCs and new Computer Accounts

Pends how quickly you join the PC to the domain after the account is created. Best solution would be to create the account on the DC in the same AD site that the pc will joined from. This will limit chances of seeing security errors because the account "doesnt" exist when infact it just hasnt replicated to that site yet.

In general, I agree - unless you have a specific reason for pre-creating the account (and there can be good, specific reasons), I wouldn't bother.  Just join it to the domain and the account will be created at the time you join.  If you do need to pre-create, it would be preferred to create on a DC in the site with the PC.  But AD should replicate fairly quickly unless you've tuned down replication making this a non-issue for all but the systems joined almost instantly after account creation.

Right, but the question is, if I just have the computer account auto create, what DC should the account appear on first by design?

Should it appear on the local DC and then replicate out, or should it appear on the PDCemu and replicate from there?

I added a machine to our domain today and I could not find it locally. I had to go to the PDCemu. Of course it replicated later, but is this initial process normal?

When you say you added a machine today, did you pre-create the account or are you in a remote site (different AD site) than your PDCe and added the machine to the domain through the machine (not pre-creating)

Thanks

Not pre-created. Added through machine.

When you join the computer to the domain, it will create the Computer object first on your physical location.
The replication will occurs as per your infrastructure...
