Re: Web NLB

I have followed directions from enclosed hyperlink (great source of
information, by the way!) on a couple test servers and have a couple issues.
Firstly, the NICs are labeled "public" and "NLB"
Lets's say my internal IP scheme is 10.0.1.* with a 255.0.0.0 subnet.
I have set up the "Public" NIC on each node as 10.0.1.47 and 10.0.1.48 with
a 255.0.0.0 subnet on each, along with the correct gateway and DNS servers.
The second NIC on each node has been configured with IPs of 192.168.1.1 and
192.168.1.2, subnet of 255.255.255.0.
I installed Network Load Balancing on each of the "public" NICs and set the
Cluster Parameter IP address on both nodes as 10.0.1.50 subnet 255.0.0.0.
Host Parameters on each reflect the "Public" NIC IP each each node with
priorities of 1 and 2, respectively. I have added 10.0.1.50 to my list of IPs
on each "Public" NIC.
I have created host records in DNS for both nodes and for the cluster.
From my workstation I can successfully ping 10.0.1.47 and 10.0.1.50 but not
10.0.1.48.
I can successfully establish a remote desktop session with both 10.0.1.47
and 10.0.1.50. When I log onto 10.0.1.50 using a remote desktop connection I
notice that the actual node that I am logged onto is 10.0.1.47.
As stated above I cannot successfully ping or establish remote desktop
session with 10.0.1.48. IP DOES resolve to correct host name when pinged but
no reply.

I have missed something somewhere
I hope that this makes sense.
Question... Why the second NIC with 192.168.1.* IP?

One Nic and only one will be configured with NLB, add the IPs to that NIC :)

Thanks Rodney!
One quick question:
When you say add as many IP as needed to the NLB NIc are you reffering to
the second NIC on each machine or the virtual NIC for the cluster?

Thanks for your help,
Dom

1. NLB is the way to go. If you are using the recommended two NICs here
are
the steps -

2. Add as many IPs as are needed to the machines on the NLB NIC. Create
additional port filtering rules as needed or assign the default rule to
all
IPs.

I am getting ready to implement two IIS servers in a NLB cluster and am
looking for a little insight before beginning this endeavor.
I have two issues that I will be addressing during this project and
would
welcome any insight (or KB articles) from anyone who has done this
before.

#1: I do NOT want servers to simply perform fail over but rather share
the
traffic between the two. We have one site that gets absolutely hammered
twice
a year and we would like to configure so that any session that is
established
will go to the least taxed server.

#2: This is the part that I am having trouble with...
We have roughly 20 sites that we host and each has it's own dedicated
IP
address (both LAN and WAN). I can find no documentation anywhere on how
best
to assign the LAN IP addresses to the load balance NIC of the cluster.

Any help at all appreciated!
Oh, by the way, we are using Server 2k3.

Thanks.
