Default NLB issue

I have conifgured network load balancing basically with two hosts and hosted a simple web application on them. The load balancing is working fine (distributing requests to the hosts) . But, I have a problem which I have described as follows.

Let us assume there are two servers A and B
I have a simple ASP.NET application which takes two inputs. I have two buttons, Next and Save. When I click on Next button, I add the values to the Viewstate and when I click on Save, the values are saved to the database.

1) Accessing server A, specify inputs, click Next button.
2) specify inputs, remove network cable from server A
3) Click Next,

Now, what is observed is that it takes some time and the request is forwarded to Server B. But, whatever data is posted is not available. Is there any possible way to overcome this?

So the next button is only putting values to viewstate. And you aren't using the session for anything correct?

In theory, you shouldn't loose anything. Posting to either server shouldn't make any difference.

Yes... Actually it works fine when we shutdown the machine (since the NLB knows that this node is not part of the cluster).

But, when we pull out the network cable, this happens.

Any help on this would be great.
