We will be installing and setting up a new domain controller by using dcpromo.exe. I think Microsoft has done a really good job at making this process pretty easy. That is unless something goes wrong when trying to remove one and you have to end up manually remove the domain controller (we won’t get into that for this article).

1. First you will goto Start -> Run -> Then type in: dcpromo

2. Now a dialog box will popup like the one below and will check to see if the Active Directory Domain Services binaries are already installed. If they are not then you will see another dialog box saying that it is currently installing them after the check.

3. Now the wizard should be started aftering checking/installing the binaries. There is an advanced mode that you could choose but for this article we will be leaving it unchecked. If you check the box you will get some more options like creating a new domain in an existing forest, but adding it to a new Domain Tree. Normally when you create a new domain it will be a child domain under the Forest Root Domain (which we are creating now)
