Prologue

Ace here again. This discusses remote administration. Simple, right? Maybe not!

Server Manager in Windows Server® 2012 R2 can be used to perform various management tasks on remote servers. By default, remote management is enabled on Windows Server 2012 R2.You can add remote servers to the Server Manager Server pool in Windows Server 2012 R2 Server Manager.

What is Remote Management?

Windows Server 2012 R2 provides the ability to remotely manage multiple servers with a number of methods. One of the newest features in Windows Server 2012 is the ability to use Server Manager for this task.

In addition to Windows Remote Management, you can also use Remote Shell and Remote Windows PowerShell to manage remote computers. This provides you the ability to locally load Windows PowerShell modules, such as Server Manager, and execute PowerShell cmdlets available in the loaded module on remote servers. This allows you the ability to run PowerShell commands and scripts. This works including when the script is only on the local server

Windows Remote Management (WinRM) is the Windows implementation of WS-Management, which is an industry standard, Web-based services based protocol. Windows runs the WinRM as a service under the same name, WinRM. WinRM provides secure local and remote communications for management applications and scripts.

In addition, Windows Remote Management is one of the components of the Windows Hardware Management features to allow secure local and remote Windows Server management across a firewall using standard Web service-based protocols.

If the server hardware has an optional, built-in Baseboard Management Controller (BMC) provided by the hardware vendor, you can also remotely manage a system even if the Windows operating system has not yet booted or has failed. This also allows access to the server’s BIOS.

A BMC is an option m provided by hardware vendors, that consists of a microcontroller and an independent network connection that you can communicate to if the server ever becomes offline.

When a server is not connected to a BMC, WinRM can still be used to connect to WMI remotely in situations where firewalls may block DCOM communications, because WinRM uses the secure web-based port, TCP 443.

How to Enable and Disable Remote Management

There are a number of methods to administer WinRM.

· Winrm.cmd – Command line tool that allows administrators to configure WinRM, get data, or manage resources. For syntax, you can run winrm /? for online help.

· Win-RM Scripting API – Allows you to create remote administration scripts that expose the WS-Management APIs and protocols.

· Winrs.exe –A command line tool to execute CMD commands on remote servers using WS-Management APIs. For example, to remotely get an ipconfig /all from a remote machine, you can run:
winrs –r:DC12.trimagna.com “ipconfig /all”;tasklist

You can also use the help command to see all possible options and syntax:
winrs –?

· IPMI and WMI Providers – The IPMI provider and drivers allow remote hardware management using BMC. These can be used programmatically.

· WMI Service – Using the WMI plug-in, WMI runs together with WinRM to provide data or control functions for remote management.

· WS-Management protocol – SOAP based protocol using XML messages. It is a web-based, firewall friendly protocol running across secure TCP 443 providing industry-standard interoperability to transfer and exchange management information.

Remote Management Tools and Commands

There are a number of ways to enable, disable and configure Remote Management.

Server Manager

To enable or disable Remote Management, in Server Manager Local Server node, click the text next to Remote Management icon.

WinRM Command

You can use the WinRM command to enable, disable, and configure Remote Management.

The syntax is:

WinRM OPERATION RESOURCE_URI [-SWITCH:VALUR [-SWITCH:VAKLUE] …] [@{KEY=VALUR [;KEP=VALUE]…}]

You can use the following to check the current Remote Management configuration and status:
winrm get winrm/config

Or you can run it remotely on another server using the WinRS command:
winrs –r:DC12-1.trimagna.com “winrm /config”;tasklist

To enable or disable Remote Management:
WinMR qc

When the WinRM qc command is run, it performs a number of steps to enable and configure the Remote Management service:

1. Configures and changes the WinRM service from Manual to Automatic startup.
2. Starts the WinRM service.
3. Creates and configures a listener that will accept WinRM requests on any IP address.
4. Creates a Windows Firewall exception for WS-Management traffic for the HTTP protocol.

If the Windows Firewall is disabled, you will see one of the following error messages:

• WSManFault
• Message
• ProviderFault
• WSManFault
• Message = Unable to check the status of the firewall.
• Error number: -2147023143 0x800706D9
• There are no more endpoints available from the endpoint mapper.

To view the command syntax and options, you can run winrm -?

WinRM supports the following commands:

• PUT
• GET
• ENUMERATION
• INVOKE

WinRM Examples:

Start a service on a remote machine:
winrm invoke startservice wmicimv2/Win32_Service?name=w32time -r:DC12

Reboot a remote machine:
winrm invoke reboot wmicimv2/Win32_OperatingSystem -r:FS1

.

PowerShell Remoting

There a number of cmdlets that use WMI for remote administration. The cmdlets invoke a temporary connection the remote computer using WMI, runs the command, then closes the session.

These cmdlets do not use WS-Management based remoting, therefore the computer does not require to be configured for WS-Management nor does it have to meet the system requirement for WS-Management. Because they are not WS-Management service related, you can use the ComputerName parameter in any of these cmdlets

You can run the Invoke-Command cmdlets to run commands on other computers.

For example, to get a list of all services on a remote computer that are either running or stopped, you can run the following command
Invoke-Command –computername DC12 –scriptblock {get-service)

Or to see the status of a single service:
Invoke-Command –computername DC12 –scriptblock {get-service WinRm)

Remote Server Administration Tools (RSAT) for Windows

Remote Server Administration Tools for Windows®  includes Server Manager, Microsoft Management Console (MMC) snap-ins, consoles, Windows PowerShell® cmdlets and providers, and some command-line tools for managing roles and features that run on Windows Server 2012 R2.

.

SCONFIG

For Server Core, you can use the SCONFIG command and choosing Option #4, then choosing Option #1 to Enable Remote Management, or Option #2 to Disable Remote Management.

Remote Desktop

Remote Desktop has been used for a number of years, and it is the most common method to remotely administer a remote machine. To use Remote Desktop, it must be enabled first on the remote computer. To enable Remote Desktop on the full version of Windows Server 2012, perform the following steps”

1. Open Server Manager
2. Click the Local Server Node
3. Click the “Disabled” status next to Remote Desktop.
4. The System Properties page appears and is focused on the Remote tab.
5. Under the Remote tab, select one of the following:

1. Don’t allow connections to this computer – Default disabled.
2. Allow connections only from Computers running:

1. Checkbox: Allow Remote Desktop with Network Level Authentication – If you check this box, this setting enables and only allows secure connections from Remote Desktop clients that support network-level authentication.

You can also enable Remote Desktop on Sever Core using the SCONFIG command.
