Managing other servers through Server Manager
The Server Manager console in Windows Server 2012 is a great improvement in my opinion over the equivalent in previous versions of Windows Server, as it allows a quick overview of the activity and health of a server through simplified versions of Event Viewer, Services and Performance Monitor all on a single page.
What’s even better is that it can be used to manage and monitor multiple servers. In a larger Enterprise environment I think System Center 2012 would be a better tool, but here where I only really need to be managing about a dozen servers it is perfect. The process to add servers to the console is very straightforward, justs click on Manage and then click Add Servers.
However like me you are likely to see a whole bunch of errors alongside the server names as below. Also please note that you can only currently add servers running Windows Server 2008 or later to the console (you can add other servers but I don’t think that they can be configured so that Server Manager can pull data or send management commands).
That’s the easy bit. The next step is to configure each of the servers that you wish to manage and monitor, information on how to do so is located at http://technet.microsoft.com/en-us/library/hh831456.aspx.
To manage servers that are running Windows Server 2008 R2 or Windows Server 2008, apply the following updates to the older operating systems.
- .NET Framework 4
- Windows Management Framework 3.0 The Windows Management Framework 3.0 download package updates Windows Management Instrumentation (WMI) providers on Windows Server 2008 and Windows Server 2008 R2. The updated WMI providers let Server Manager collect information about roles and features that are installed on the managed servers. Until the update is applied, servers that are running Windows Server 2008 or Windows Server 2008 R2 have a manageability status of Not accessible – Verify earlier versions run Windows Management Framework 3.0.
- The performance update associated with Knowledge Base article 2682011 allows Server Manager to collect performance data from Windows Server 2008 and Windows Server 2008 R2.
However I was still getting the same error message even after installing the three required updates. I verified that the WinRM service was running and so concluded that the firewall was blocking the data. The resolution was to run the command
WinRM quickconfig on the server that is to be managed and this then creates a WinRM listener to accept WS-Man requests and creates an exception in the Windows Firewall. The command and output is shown below.
Having configured the server VS022-INFRAS thusly you can now see that the message has changed to Online. Just need to enable the performance counters and then I can move onto configuring the other servers (though it will need to be an out of hours job as the servers are production servers or critical test servers that I can’t restart during normal hours.)
