When installing Windows Server 2008 R2, you do not get the option to configure the computername, IP and domainmembership during setup (When not using a Unattended Setup). So these tasks need to be done ones the installation finishes.
Following commands allow you configure these settings using the command Line Interface.
Rename the computer:
Netdom Renamecomputer %Computername% /Newname:Computername
(Requires a reboot)
Configure the Local area connection
Netsh interface ip set address name="Local Area Connection" Static 192.168.1.1 255.255.255.0 192.168.1.254
Explination: "Netsh interface ip set address name="Local Area Connection" Static Ipaddress Subnetmask Defaultgateway"
Netsh Interface IP Set DNS "Local Area Connection" Static 192.168.1.10
Explination: "Netsh interface ip set DNS "Local Area Connection" Static Ipaddress Dns Server
Configure Domain Membership
Netdom Join %Computername% /Domain:Domainname /UserD:Administrator /PasswordD:*
By Specifying the asterix in the Password (*) the CLI will promt you for a password.
Shutdown -r -t 0
By using the %Computername% variable you do not need to check the computername.
