In the previous post in this mini-series, we configured each of our Management Servers with a static IP Address. Now we will enable NLB on each Management Server, by first installing the Network Load Balancing feature.
To use Network Load Balancing (NLB), a computer must have only TCP/IP on the adapter on which NLB is installed. Do not add any other protocols (for example, IPX) to this adapter. NLB can load balance any application or service that uses TCP/IP as its network protocol and is associated with a specific Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) port.
To install and configure NLB, you must use an account that is listed in the Administrators group on each host. If you are not using an account in the Administrators group as you install and configure each host, you will be prompted to provide the logon credentials for such an account. To set up an account that NLB Manager will use by default: in NLB Manager, expand the Options menu, and then click Credentials. We recommend that this account not be used for any other purpose.
As a reminder, we’ll break the articles/posts down into smaller pieces. Here is a high-level of each piece.
Let’s start with the second step.
Enable NLB on each Management Server > Install Network Load Balancing
The first thing we need to do is install the Network Load Balance feature on each Management Server.
Let’s log into our first Management Server, and install the feature.
Start by launching Server Manager, then click Add Roles and Features.
In the Add Roles and Features Wizard, on the Before You Begin screen, read the information presented, then click Next.
On the Installation Type screen, ensure that “Role-based or feature-based installation” is selected, then click Next.
On the Server Selection screen, the local server should be selected, then click Next.
On the Server Roles screen, don’t select anything, and then click Next.
On the Features screen, scroll down the list and find “Network Load Balancing” and select it.
You will encounter the following prompt to install additional features that are required with the Network Load Balancing feature. Click Add Features.
Back on the Features screen, the Network Load Balancing feature should now appear selected. Then click Next.
On the Confirmation screen, click Install.
Once the installation is completed, click Close.
Now our first Management Server has the Network Load Balancing feature installed, repeat these same steps on any other Management Servers you want to include in the cluster.
In the next post in this series, we will move onto Step 3: Enable NLB on each Management Server > Create A NLB Cluster.
