How To Windows 2008 NLB Part 1

 

Using NLB is very handy on several configurations ( but remember there is a lot of broadcast trafic ) so the nlb network should be in a different subnet than your own production network.

First add the feature in windows 2008 , start up the NLB mmc on the server.

In my care I have 3 nic , one production , two DHCP.

I did new cluster and the wizzard starts. I did pick the second nic.

The warning is I NEED a fixed IP !!  so i put in a fix IP and added the cluster IP address

Most of the times You don’t need every port on the nic , for webservers it is only one or two ports. I my case I used the opsmgr webconsole basic port 51908.

Now One host is ready to go.

I went to my IIS 7 MMC

For changing the IP you do on the website edit bindings get the default. And Edit the settings.

As you can see the NLB cluster IP is there I did not config a second IP for the NLB . So I put in the NLB IP and now the website is listening on the NLB IP. AND NOT on the default IP from the server.

 

So If you want to add a second IP to the NLB go back to the NLB config an do edit on the cluster properties

clip_image042 as you can see the IIS config shows the second IP clip_image044

This could be handy for large webfarms that uses hostheaders.

For Setting up the Second , thirth node just add the machine in the cluster Add host and settings are deployed to the other server.

Fixed IP is needed !!
