Install NLB on Windows Server 2008 R2 Core Installation

1. Open  an elevated command prompt and run > dism /online /Enable-feature /featurename:NetworkLoadBalancingHeadlessServer

Note that you may need to launch a new command prompt with administrative privileges using the RunAs command.

PowerShell

By default, Server Core does not have management tools such as Nlbmgr.exe or PowerShell CMDlets installed, thus you may want to manage NLB from a remote server.  If you want to manage NLB on Server Core locally you must install PowerShell which will include cmdlets for NLB.  To install PowerShell in Server Core run the following commands.

1. From a command prompt, run > dism /online /Enable-feature /featurename:NetFx2-ServerCore  

Note that you may need to launch a new command prompt with administrative privileges using the RunAs command.

2. Then run > dism /online /Enable-feature /featurename:MicrosoftWindowsPowershell

3. If NLB is not installed, install NLB as described in the section above, ‘Install NLB on Windows Server 2008 R2 Core Installation’
