Administer a Server Core server
Applies To: Windows Server (Semi-Annual Channel) and Windows Server 2016
Because Server Core doesn't have a UI, you need to use Windows PowerShell cmdlets, command line tools, or remote tools to perform basic administration tasks. The following sections outline the PowerShell cmdlets and commands used for basic tasks. You can also use Windows Admin Center, a unified management portal currently in public preview, to administer your installation.
Administrative tasks using PowerShell cmdlets
Use the following information to perform basic administrative tasks with Windows PowerShell cmdlets.
Set a static IP address
When you install a Server Core server, by default it has A DHCP address. If you need a static IP address, you can set it using the following steps.
To view your current network configuration, use Get-NetIPConfiguration.
To view the IP addresses you're already using, use Get-NetIPAddress.
To set a static IP address, do the following:
Note the number in the IfIndex column for your IP interface or the InterfaceDescription string. If you have more than one network adapter, note the number or string corresponding to the interface you want to set the static IP address for.
Run the following cmdlet to set the static IP address:
New-NetIPaddress -InterfaceIndex 12 -IPAddress 192.0.2.2 -PrefixLength 24 -DefaultGateway 192.0.2.1
- InterfaceIndex is the value of IfIndex from step 2. (In our example, 12)
- IPAddress is the static IP address you want to set. (In our example, 184.108.40.206)
- PrefixLength is the prefix length (another form of subnet mask) for the IP address you're setting. (For our example, 24)
- DefaultGateway is the IP address to the default gateway. (For our example, 192.0.2.1)
Run the following cmdlet to set the DNS client server address:
Set-DNSClientServerAddress –InterfaceIndex 12 -ServerAddresses 192.0.2.4
- InterfaceIndex is the value of IfIndex from step 2.
- ServerAddresses is the IP address of your DNS server.
To add multiple DNS servers, run the following cmdlet:
Set-DNSClientServerAddress –InterfaceIndex 12 -ServerAddresses 192.0.2.4,192.0.2.5
where, in this example, 192.0.2.4 and 192.0.2.5 are both IP addresses of DNS servers.
If you need to switch to using DHCP, run Set-DnsClientServerAddress –InterfaceIndex 12 –ResetServerAddresses.
Join a domain
Use the following cmdlets to join a computer to a domain.
Run Add-Computer. You'll be prompted for both credentials to join the domain and the domain name.
If you need to add a domain user account to the local Administrators group, run the following command at a command prompt (not in the PowerShell window):
net localgroup administrators /add <DomainName>\<UserName>
Restart the computer. You can do this by running Restart-Computer.
Rename the server
Use the following steps to rename the server.
- Determine the current name of the server with the hostname or ipconfig command.
- Run Rename-Computer -ComputerName <new_name>.
- Restart the computer.
Activate the server
Run slmgr.vbs –ipk<productkey>. Then run slmgr.vbs –ato. If activation succeeds, you won't get a message.
You can also activate the server by phone, using a Key Management Service (KMS) server, or remotely. To activate remotely, run the following cmdlet from a remote computer:
**cscript windows\system32\slmgr.vbs <ServerName> <UserName> <password>:-ato**
Configure Windows Firewall
You can configure Windows Firewall locally on the Server Core computer using Windows PowerShell cmdlets and scripts. See NetSecurity for the cmdlets you can use to configure Windows Firewall.
Enable Windows PowerShell remoting
You can enable Windows PowerShell Remoting, in which commands typed in Windows PowerShell on one computer run on another computer. Enable Windows PowerShell Remoting with Enable-PSRemoting.
For more information, see About Remote FAQ.
Administrative tasks from the command line
Use the following reference information to perform administrative tasks from the command line.
Configuration and installation
|Set the local administrative password||net user administrator *|
|Join a computer to a domain||netdom join %computername% /domain:<domain> /userd:<domain\username> /passwordd:*
Restart the computer.
|Confirm that the domain has changed||set|
|Remove a computer from a domain||netdom remove <computername>|
|Add a user to the local Administrators group||net localgroup Administrators /add <domain\username>|
|Remove a user from the local Administrators group||net localgroup Administrators /delete <domain\username>|
|Add a user to the local computer||net user <domain\username> * /add|
|Add a group to the local computer||net localgroup <group name> /add|
|Change the name of a domain-joined computer||netdom renamecomputer %computername% /NewName:<new computer name> /userd:<domain\username> /passwordd: *|
|Confirm the new computer name||set|
|Change the name of a computer in a work group||netdom renamecomputer <currentcomputername> /NewName:<newcomputername>
Restart the computer.
|Disable paging file management||wmic computersystem where name="<computername>" set AutomaticManagedPagefile=False|
|Configure the paging file||wmic pagefileset where name=”<path/filename>” set InitialSize=<initialsize>,MaximumSize=<maxsize>
Where path/filename is the path to and name of the paging file, initialsize is the starting size of the paging file, in bytes, and maxsize is the maximum size of the page file, in bytes.
|Change to a static IP address||ipconfig /all
Record the relevant information or redirect it to a text file (ipconfig /all >ipconfig.txt).
netsh interface ipv4 show interfaces
Verify that there is an interface list.
netsh interface ipv4 set address name <ID from interface list> source=static address=<preferred IP address> gateway=<gateway address>
Run ipconfig /all to verify that DHCP enabled is set to No.
|Set a static DNS address.||netsh interface ipv4 add dnsserver name=<name or ID of the network interface card> address=<IP address of the primary DNS server> index=1
netsh interface ipv4 add dnsserver name=<name of secondary DNS server> address=<IP address of the secondary DNS server> index=2**
Repeat as appropriate to add additional servers.
Run ipconfig /all to verify that the addresses are correct.
|Change to a DHCP-provided IP address from a static IP address||netsh interface ipv4 set address name=<IP address of local system> source=DHCP
Run ipconfig /all to verify that DCHP enabled is set to Yes.
|Enter a product key||slmgr.vbs –ipk <product key>|
|Activate the server locally||slmgr.vbs -ato|
|Activate the server remotely||cscript slmgr.vbs –ipk <product key><server name><username><password>
cscript slmgr.vbs -ato <servername> <username> <password>
Get the GUID of the computer by running cscript slmgr.vbs -did
Run cscript slmgr.vbs -dli <GUID>
Verify that License status is set to Licensed (activated).
Networking and firewall
|Configure your server to use a proxy server||netsh Winhttp set proxy <servername>:<port number>
Note: Server Core installations can't access the Internet through a proxy that requires a password to allow connections.
