Re: Network Load Balancing Problem



I create my NLB cluster by NLBManager in one of two machine that
are in workgroup domain.

With NLB manager of win2003 server i need to install loopback adapter
or no?

Again, where are you testing from? One of the machines that has NLB loaded
or an Admin machine?

Cheers,

Are you trying to test NLB from one of the NLB machines? If so try a
machine on the DMZ network. You will also need to check for a new
version of the page Every time I visit the webpage (or hit F5/refresh).

If the machines have converged, it should be working. Try reloading the
pages via script 10-20 times and you should see some interesting
results. Even with even balanced, 20 hits will result in 14 on one, 6 on
the other or something close to that - hardly ever 10-10.

Hello ,

my name is Fabio ,
i have a problem with the "fast load balancing solution of
Microsoft".

I have 2 web server (standard edition) in workgroup, wired with two
network card
in two switch (layer 2, not router).

DMZ LAN
Server 1 10.10.10.57 10.10.20.57
Server 2 10.10.10.52 10.10.20.52

With NLB manager in the Server1 i create new cluster

cluster.x.y 10.10.10.60

unicast mode
rules port 80 affinity single

Then i add first (local) host ,
when i add the second host i need to use the local admin grants with
this

10.10.10.52\administrator password

Then all of the host are converged,

In the all IIS admin i create the same site, with same file etc

In the firewall i create the static NAT line for the 10.10.10.60 IP ;
when i try to open the url of my example page
the cluster response only with the second host, if i stopped this
service or i shutdown this second host my
example page don't open.

where is the mistake?

Thanks a lot

Fabio Cecaro
