sys.webforms.pagerequestmanagerTimeoutException
<p>I deployed my application to windows server 2008. I tested my application on the server and everything is working fine on the server itself. The client machine attached to the server has wndows 7 on it. I went to the application by typing the IP address of the server and access the application</p>

<p><a href="http://IP">http://IP</a> adress/login.aspx</p>

<p>On one of my page, I have a master slave drop downs, when I select something from one of the drop down then based on the seletion, my second drop down is populated. This is working fine on server machine, but on client machine, I am getting an error saying</p>

<pre><code>Sys.Webforms.PageRequestManagerTimeoutException
</code></pre>

<p>The server request timed out.
I goggled the issue and ajax seemed to be the probelm. I put the following code in my page load:</p>

<pre><code>protected void Page_Load(object sender, EventArgs e)
{
    ScriptManager ScriptManager1 = (ScriptManager)Master.FindControl("ScriptManager1");
    ScriptManager1.AsyncPostBackTimeout = 37000000;
    if (!IsPostBack)
    {
        loadAvailableGroupNames();
       // LoadAvailableSystems();

    }
 }
</code></pre>

<p>I am still getting the timeout exception only on client machine. My client machine has IE 9 and windows 7 on it.</p>

<p>any help will be appreciated.</p>
