Configuring Windows Server 2008 Server Core Basic Networking Settings

Daniel Petri

Jan 7, 2009

In my previous articles (see list below) I have written about how, in Windows Server 2008, Server Core installation does not include the traditional full graphical user interface (GUI). Therefore, once you have configured the server, you can only manage it locally at a command prompt, or remotely using a Terminal Server connection. Read more about Server Core on my “Understanding Windows Server 2008 Server Core” article.

Like any other server, Server Core machines must be properly configured to be able to communicate on your network. Some of these settings include:

Configuring an IP address
Configuring an administrator’s password
Configuring a server name
Enabling remote MMC snap-in management
Enabling remote RDP connections
Enabling remote Windows Firewall management
Enabling remote shell management
Activating the server
Joining a domain
Configuring Windows Updates
Configuring error reporting
Adding server roles and features

And other tasks.
Before you start, you need to configure the server’s IP address.

advertisment

To set the server with a static IP address

At a command prompt, type the following:
```
netsh interface ipv4 show interfaces
```
Look at 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.
At the command prompt, type:
```
netsh interface ipv4 set address name="" source=static address= mask= gateway=
```
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
At the command prompt, type:
```
netsh interface ipv4 add dnsserver name="" address= index=1
```
Where:
- ID is the number from step 2 above
- DNSIP is the IP address of your DNS server
Repeat step 4 for each DNS server that you want to set, incrementing the index= number each time.
Verify by typing ipconfig /all and checking that all the addresses are correct.

To set the administrative password in Windows Server 2008

At a command prompt, type the following:
```
net user administrator *
```
When prompted to enter the password, type the new password for the administrator user account and press ENTER.
When prompted, retype the password and press ENTER.

Next, you might want to change the computer’s name, as the default name is a random-generated name (unless configured through an answer file)

To change the name of the server

Determine the current name of the server with the hostname or ipconfig /all commands.
At a command prompt, type:
```
netdom renamecomputer  /NewName:
```
Restart the computer by typing the following at a command prompt:
```
shutdown /r /t 0
```

To manage a server running a Server Core installation by using the Windows Remote Shell

To enable Windows Remote Shell on a server running a Server Core installation, type the following command at a command prompt:
```
WinRM quickconfig
```
Click Y to accept the default settings. Note: The WinRM quickconfig setting enables a server running a Server Core installation to accept Windows Remote Shell connections.
3. On the remote computer, at a command prompt, use WinRS.exe to run commands on a server running a Server Core installation. For example, to perform a directory listing of the Windows folder, type:
```
winrs -r: cmd
```
Where ServerName is the name of the server running a Server Core installation.
You can now type any command that you require, it will be executed on the remote computer.

To activate the server

At a command prompt, type:
```
slmgr.vbs –ato
```
If activation is successful, no message will return in the command prompt.

To activate the server remotely

At a command prompt, type:
```
cscript slmgr.vbs -ato
```
Retrieve the GUID of the computer by typing:
```
cscript slmgr.vbs -did
```
Type
```
cscript slmgr.vbs -dli
```
Verify that License status is set to Licensed (activated).

To join a Windows 2008 server to a domain

At a command prompt, type:
```
netdom join  /domain: /userd: /passwordd:*
```
Where:

advertisment
- 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.
Note: Entering * as the password means you will be prompted to enter it on the command prompt window in the next step. You can enter it in the initial command, if you wish to. Note: Note that the word “passwordd” has 2 d’s in it…
When prompted to enter the password, type the password for the domain user account specified by UserName.
Restart the computer by typing the following at a command prompt:
```
shutdown /r /t 0
```

To remove the Windows 2008 server from a domain

At a command prompt, type:
```
netdom remove
```
Reboot the computer.

To configure automatic updates

To enable automatic updates, type:

cscript C:'Windows'System32'Scregedit.wsf /au 4

To disable automatic updates, type:

cscript C:'Windows'System32'Scregedit.wsf /au 1

BTW, in order to view your current settings you can type:

cscript C:'Windows'System32'Scregedit.wsf /au /v

To configure error reporting

To verify the current setting, type:
```
serverWerOptin /query
```
To automatically send detailed reports, type:
```
serverWerOptin /detailed
```
To automatically send summary reports, type:
```
serverWerOptin /summary
```
To disable error reporting, type:
```
serverWerOptin /disable
```

Summary

Windows Server 2008 Core machines need to be properly configured for communication across your network. While most of the Server Core settings need to be configured via the local Command Prompt, some settings can also be configured remotely. This article, a part of a complete Server Core article series, will show you how to do that.
