Server Core Installation Option of Windows Server 2008 Step-By-Step Guide

This step-by-step guide provides instructions for building a server in your test lab that is based on the Server Core installation option of the Windows Server® 2008 operating system. It includes information about installation, initial configuration, and managing a server that is running a Server Core installation.

What is a Server Core installation?

The Server Core installation option is a new option that you can use for installing Windows Server 2008. A Server Core installation provides a minimal environment for running specific server roles, which reduces the maintenance and management requirements and the attack surface for those server roles. A server running a Server Core installation supports the following server roles:

Active Directory Domain Services (AD DS)

Active Directory Lightweight Directory Services (AD LDS)

DHCP Server

DNS Server

File Services

Hyper-V

Print Services

Streaming Media Services

Web Server (IIS)

To accomplish this, the Server Core installation option installs only the subset of the binary files that are required by the supported server roles. For example, the Explorer shell is not installed as part of a Server Core installation. Instead, the default user interface for a server running a Server Core installation is the command prompt.

What’s new in the Server Core installation option?

The Server Core installation option of Windows Server 2008 requires initial configuration at a command prompt. A Server Core installation does not include the traditional full graphical user interface. Once you have configured the server, you can manage it locally at a command prompt or remotely using a Terminal Server connection. You can also manage the server remotely using the Microsoft Management Console (MMC) or command-line tools that support remote use.

Who should use this guide?

The target audience for the Server Core installation option of Windows Server 2008 includes:

IT planners and analysts who are technically evaluating the product.

Enterprise IT planners and designers for organizations.

IT professionals who are managing the AD DS, AD LDS, DHCP Server, DNS Server, File Services, Print Services, Streaming Media Services, and Web Server (IIS) roles.

Benefits of a Server Core installation

The Server Core installation option of Windows Server 2008 provides the following benefits:

Reduced maintenance. Because the Server Core installation option installs only what is required to have a manageable server for the AD DS, AD LDS, DHCP Server, DNS Server, File Services, Print Services, and Streaming Media Services roles, less maintenance is required than on a full installation of Windows Server 2008.

Reduced attack surface. Because Server Core installations are minimal, there are fewer applications running on the server, which decreases the attack surface.

Reduced management. Because fewer applications and services are installed on a server running the Server Core installation, there is less to manage.

Less disk space required. A Server Core installation requires only about 1 gigabyte (GB) of disk space to install and approximately 2 GB for operations after the installation.

Using an unattend file to install a Server Core installation

Using an unattend file for a Server Core installation enables you to perform most of the initial configuration tasks during Setup. Performing an unattended Server Core installation provides the following benefits:

There is no need to perform the initial configuration by using command-line tools.

You can include the settings in the unattend file to enable remote administration (when Setup is complete).

You can configure settings that cannot be easily modified at a command prompt, such as display resolution.

To install a Server Core installation by using an unattend file

1.

Create a .xml file titled Unattend.xml by using a text editor or Windows System Image Manager.

2.

Copy the Unattend.xml file to a local drive or shared network resource.

3.

Boot your computer to Windows Preinstallation Environment (Windows PE), Windows Server 2003, or Windows XP.

4.

Insert the media disk with the Server Core installation of Windows Server 2008 into your disk drive. If the auto-run Setup window appears, click Cancel.

5.

At a command prompt, change to the drive that contains the installation media.

6.

Type the following at a command prompt:

setup /unattend:<path>\unattend.xml

where path is the path to your Unattend.xml file.

Configuring a Server Core installation: Overview

Because a Server Core installation does not include the Windows user interface, there is no "out-of-box experience" to help you complete the server configuration. Instead you must manually complete the configuration using the command-line tools as outlined in the following steps.

Note:

You can use an unattended setup to configure these settings during installation. For more information about unattended settings, see the Windows Automated Installation Kit (Windows AIK) (http://go.microsoft.com/fwlink/?LinkId=81030).

Administrative credentials

If you are going to join a server running a Server Core installation to an existing Windows domain, you need a user name and password for an account that has the administrative credentials to join a computer to the domain.

Known issues for configuring a Server Core installation

If you close all command prompts, you will have no way to manage the Server Core installation. To recover, you can press CTRL+ALT+DELETE, click Start Task Manager, click File, click Run, and type cmd.exe. Alternatively, you can log off and log back on again.

Because there is no Web browser, you cannot activate a Server Core installation or access the Internet through a firewall that requires users to log on.

Steps for configuring a Server Core installation

The following procedures explain how to configure a computer running a Server Core installation. The steps include:

Setting the administrative password

Setting a static IP address

Note:

A DHCP address is provided by default. You should perform this procedure only if you need to set a static IP address.

Joining a domain

Activating the server

Configuring the firewall

To set the administrative password

1.

When your computer starts for the first time after the installation completes, press CTRL+ALT+DELETE. Type Administrator for the user name and leave the password blank.

2.

The system will inform you that the password has expired and will prompt you to enter a new password.

3.

Type an appropriate password.

To set a static IP address

1.

At a command prompt, type the following:

netsh interface ipv4 show interfaces

2.

Make a note of the number shown in the Idx column of the output for your network adapter. If your computer has more than one network adapter, make a note of the number corresponding to the network adapter for which you wish to set a static IP address.

3.

At the command prompt, type:

netsh interface ipv4 set address name="<ID>" source=static address=<StaticIP> mask=<SubnetMask> gateway=<DefaultGateway>

Where:

ID is the number from step 2 above

StaticIP is the static IP address that you are setting

SubnetMask is the subnet mask for the IP address

DefaultGateway is the default gateway

4.

At the command prompt, type:

netsh interface ipv4 add dnsserver name="<ID>" address=<DNSIP>index=1

Where:

ID is the number from step 2 above

DNSIP is the IP address of your DNS server

5.

Repeat step 4 for each DNS server that you want to set, incrementing the index= number each time.

Note:

If you set the static IP address on the wrong network adapter, you can change back to using the DHCP address supplied by using the following command:

netsh interface ipv4 set address name="<ID>" source=dhcp

where ID is the number of the network adapter from Step 2.

To join a domain

1.

At a command prompt, type:

netdom join <ComputerName> /domain:<DomainName> /userd:<UserName> /password:*

Where:

ComputerName is the name of the server that is running the Server Core installation.

DomainName is the name of the domain to join.

UserName is a domain user account with permission to join the domain.

2.

When prompted to enter the password, type the password for the domain user account specified by UserName.

3.

If you need to add a domain user account to the local Administrators group, type the following command:

net localgroup administrators /add <DomainName>\<UserName>

4.

Restart the computer. You can do this by typing the following at a command prompt:

shutdown /r /t 0

To rename the server

1.

Determine the current name of the server with the hostname or ipconfig command.

2.

At a command prompt, type:

Managing a Server Core installation: Overview

You can manage a server running Server Core installation in the following ways:

Locally and remotely using a command prompt. By using the Windows command-line tools at a command prompt, you can manage servers running a Server Core installation.

Remotely using Terminal Server. By using another computer running Windows, you can use the Terminal Server client to connect to a server running a Server Core installation, and manage it remotely. The shell in the Terminal Server session will be the command prompt.

Remotely using Windows Remote Shell. By using another computer running Windows Vista or Windows Server 2008, you can use Windows Remote Shell to run command-line tools and scripts on a server running a Server Core installation.

Remotely using an MMC snap-in. By using an MMC snap-in from a computer running Windows Vista or Windows Server 2008, you can connect to a server running Server Core installation in the same way that you would connect to any computer running Windows.

Prerequisites for managing a server running Server Core installation

To manage a server running Server Core installation, you need:

A computer that has a Server Core installation of Windows Server 2008 installed and configured.

An administrator user account and password for a server running a Server Core installation.

Top of pageTop of page

Known issues for managing a server running a Server Core installation

Not all tasks can be performed at a command prompt or remotely through an MMC snap-in. There is a script included with the Server Core installation of Windows Server 2008 that you can use to configure the following settings:

Enable automatic updates

Enable Remote Desktop for Administration

Enable Terminal Server clients on previous versions of Windows to connect to a server running a Server Core installation

Configure DNS SRV record weight and priority

Manage IPsec Monitor remotely

The script is located in the \Windows\System32 folder of a server running a Server Core installation. At a command prompt, open the folder, and then use the following command to display the usage instructions for the previous options:

cscript scregedit.wsf /?

ServerName is the name of the server running a Server Core installation.

Note:

The WinRM quickconfig setting enables a server running a Server Core installation to accept Windows Remote Shell connections. This setting can also be set in an unattend file. See the example in Appendix A at the end of this document.

Important:

For more information about using different security credentials to run commands, see the command-line help for WinRS.exe by typing winrs -? at a command prompt.

 

To manage a server that is running a Server Core installation and is a domain member using an MMC snap-in

1.

Start an MMC snap-in, such as Computer Management.

2.

In the left pane, right-click the top of the tree and click Connect to another computer. (In the Computer Management example, you would right-click Computer Management (Local).)

3.

In Another computer, type the computer name of the server running a Server Core installation and click OK.

4.

You can now use the MMC snap-in to manage the server running a Server Core installation as you would any other computer running a Windows Server operating system.

To manage a server that is running a Server Core installation and is not a domain member using an MMC snap-in

1.

If the server running a Server Core installation is not a member of a domain, establish alternate credentials to use to connect to the Server Core installation by typing the following command at a command prompt on your client computer:

cmdkey /add:<ServerName> /user:<UserName> /pass:<password>

Where:

ServerName is the name of the server running a Server Core installation.

UserName is the name of an administrator account.

To be prompted for a password, omit the /pass option.

2.

When prompted, type the password for the user name that is specified in the previous step.

3.

If the firewall on the computer running a Server Core installation is not already configured to allow MMC snap-ins to connect, follow the steps in "To configure Windows Firewall to allow MMC snap-in(s) to connect." Then return to this procedure.

4.

On a different computer, start an MMC snap-in, such as Computer Management.

5.

In the left pane, right-click the top of the tree and click Connect to another computer. (In the Computer Management example, you would right-click Computer Management (Local).)

6.

In Another computer, type the computer name of the server running a Server Core installation and click OK.

7.

You can now use the MMC snap-in to manage the server running a Server Core installation as you would any other computer running a Windows Server operating system.

1.

To allow all MMC snap-ins to connect, at a command prompt, type:

Netsh advfirewall firewall set rule group=“remote administration” new enable=yes

2.

To allow only specific MMC snap-ins to connect, at a command prompt, type:

Netsh advfirewall firewall set rule group=“<rulegroup>” new enable=yes

Where:

Rulegroup is one of the values from the table below, depending on which snap-in you want to connect.

Note:

Some MMC snap-ins do not have a corresponding rule group that allows them to connect through the firewall. However, enabling the rule groups for Event Viewer, Services, or Shared Folders will allow most other snap-ins to connect.

Additionally, certain snap-ins require further configuration before they can connect through the firewall:

Device Manager. You must first enable the Allow remote access to the PnP interface policy setting. To do this, on a computer running Windows Vista or a full installation of Windows Server 2008, open the Local Group Policy Editor MMC snap-in, connect to the computer running a Server Core installation, navigate to Computer Configuration\Administrative Templates\Device Installation, and then enable Allow remote access to the PnP interface. Restart the computer running a Server Core installation.

Note that when Device Manager is used remotely, it is read-only.

Disk Management. You must first start the Virtual Disk Service (VDS) on the computer running a Server Core installation. You must also configure the Disk Management rules appropriately on the computer that is running the MMC snap-in.

IP Security Monitor. You must first enable remote management of this snap-in. To do this, at a command prompt, type:

Cscript \windows\system32\scregedit.wsf /im 1

Reliability and Performance. The snap-in does not require any further configuration, but when you use it to monitor a computer running a Server Core installation, you can only monitor performance data. Reliability data is not available.

To add hardware to a server running a Server Core installation

1.

Follow the instructions provided by the hardware vendor for installing new hardware:

If the driver for the hardware is included in Windows Server 2008, Plug and Play will start and install the driver.

If the driver for the hardware is not included, proceed with the steps 2 and 3.

2.

Copy the driver files to a temporary folder on the server running a Server Core installation.

3.

At a command prompt, open the folder where the driver files are located, and then run the following command:

pnputil -i -a <driverinf>

Where:

driverinf is the file name of the .inf file for the driver.

4.

If prompted, restart the computer.

To obtain a list of drivers that are installed on the server running a Server Core installation

At a command prompt, type:

sc query type= driver

Note:

You must include the space after the equal sign for the command to complete successfully.

To disable a device driver on a server running a Server Core installation

At a command prompt, type:

sc delete <service_name>

Where:

service_name is the name of the service that you obtain by running sc query type= driver.
