Sorry, I wasn't clear enough. I was trying to ask if you know what is going on with your server. 30 seconds is a pretty long time to wait for a repsonse.

Hi Miruna, 

There is nothing wrong with the server. 

The form that I am trying to 'Retrieve Values' from is a very big form with more than 1000 fields and lots of JavaScripts and CSS. That might be causing the time out when retrieving the values. 

JavaScript and CSS are not loaded when Workflow retrieves the form fields. But 1000 fields is a lot.

In the Workflow Designer's config file (C:\Program Files\Laserfiche\Laserfiche Workflow 9\Laserfiche.Workflow.Designer.exe.config), look for a section that looks like this:

<bindings>
      <netTcpBinding>
        <binding name="ConfigurationClientBinding" transferMode="Streamed"
          maxBufferSize="1000" maxReceivedMessageSize="67108864">
          <readerQuotas maxStringContentLength="1024000000" maxArrayLength="1024000000" />
        </binding>
      </netTcpBinding>
    </bindings>

and add the following after maxReceivedMessageSize:  receiveTimeout="00:01:00" sendTimeout="00:01:00"

<bindings>
      <netTcpBinding>
        <binding name="ConfigurationClientBinding" transferMode="Streamed"
          maxBufferSize="1000" maxReceivedMessageSize="67108864" receiveTimeout="00:01:00" sendTimeout="00:01:00">
          <readerQuotas maxStringContentLength="1024000000" maxArrayLength="1024000000" />
        </binding>
      </netTcpBinding>
    </bindings>

You may have to try different values to see what works out for such a large form.

Out of curiousity, why do users need to see 1000 fields in a single form?

I tried the solution suggested above, but it did not work. 

We are using this form to contract with new Healthcare Providers. Contracting process is lengthy and we need to collect lot of information about the provider, hence the form is very big. 

This solution worked for me.  I had to restart the Workflow service after making the config change.
