01 build a root DC on Windows Server 2008R2
First priority: work environment preparation
1. Configure the IP address (the IP address of your root DC. The DNS address must be specified, and the gateway can be ignored first), as shown below:
2. Configure the installation wizard for AD
Click add. NET Framework 3.5.1
The configuration wizard for AD has been added
3. Install the first root DC
Install AD, this AD is the first AD of the domain controller, the root AD, and also the first domain controller (DC). The graphical installation I use here is very smooth, as shown below:
It should be noted that because the first root DC is built here, "choose to build a new domain in the new forest".
Get a domain name for the root DC: for example: contoso.com
It should be noted here that when selecting the forest function level, you need to consider whether the servers in your own company still have windows server 2003. If so, the forest function level here can choose the lowest level of windows server 2003, which is convenient for future windows server 2003 server upgrades. I choose a higher level here in order to give full play to its performance, so I designed it this way. Just think about it when you choose.
This prompt appears here, do not be afraid, this is a normal thing, this is because I did not build a DNS server in advance when building DC, and in general, it is not recommended to build DNS in advance, so the trouble of comparison may also lead to errors in building DC later, so install the DNS server when building DC, so you can avoid reporting errors and reduce the installation process. Kill two birds with one stone, so click "Yes" here.
It should be noted in this place that the restoring password of the root DC server needs to be provided when uninstalling DC, so this password must be saved well, complicated, and it doesn't matter to forget, otherwise the consequences will be very great.
At this stage, the installation is very smooth.
The DNS host record of the built root DC
The change of the computer working group, which used to be "working group: workgroup", is now "domain: contosoto.com". Here, the first root DC has been built.
