production network card is not the first bound network card

Often when you do a validation health check the first nic is not the first nic and you did check it in the network options. There is a way to change this or to checkit.

You can change it in the advanced settings with the up down arrow.

Do this with WMI

Open a admin Command prompt in the search/run type CMD and instead of hitting the Enter key, use Ctrl+Shift + Enter this opens the Admin CMD.

Now Run :

wmic nicconfig get description, SettingID > C:\nicguidconfig.txt

Lookup the nicguidconfig.txt

It looks like this :

Now that we have the Guid we go to the Register and look it up :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Linkage\Bind

Open the Bind

Cut and paste GUID’s so that production network card (or NIC team) is at the top of the list.

Save key and confirm binding is correct via ipconfig /all

Your Done

Change IIS 7.5 Website ID

If you are building a Webfarm just make sure Your Website ID is the same on your farm.

To change the ID just run the APPCMD

the Sample below I have 3 websites that I want to change the ID

Just change the Web01 with your website and ID I Change the Web01 form ID 40 to 10

appcmd set site Web01 /id:40
appcmd set site Web02 /id:50
appcmd set site Web03 /id:60
appcmd set site Web01 /id:10
appcmd set site Web02 /id:20
appcmd set site Web03 /id:30

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

as you can see the IIS config shows the second IP
