Problem with TCP Channel already registred .net remoting (.net 1.0, IIS)

[Martijn Damen]

Hi,

At the moment I am trying to develop an application that uses another app
over .net remoting and having some problems with it (ok, that is ofcourse
why I am here), hope somebody can shine a light on the following:

I have been given a sample winforms app, which works without problem, I can
connect, send queries and become response from the other application.

When I try to implement this in webforms, this unfortunately does not work.

What I do in my index.aspx.cs is this:

private void Page_Load(object sender, System.EventArgs e)
{
RemotingConfiguration.Configure(Server.MapPath("Web.config"));
connection = new Connection();
}

Where Connection() is a part of included references, which are especially
made to connect to the server application

In my web.config I added following configuration:

<system.runtime.remoting>

<application>

<lifetime leaseTime="24H" sponsorshipTimeout="30S" renewOnCallTime="60H"
leaseManagerPollTime="1H" />
<client url="tcp://xxx.xxx.xxx.xxx:1234" displayName="some.Session">
<activated type="some.name.Connection, some.Core" />
<activated type="some.name.Connection, some.Index" />
</client>
<client url="tcp://xxx.xxx.xxx.xxx:1234/someWorkflowServer">
<activated type="some.name.Connection, some.Workflow"/>
</client>
<channels>
<channel ref="tcp client" />
</channels>
</application>
</system.runtime.remoting>

When I try to make the connection my local installed webserver gives me
following error time after time:

Does anybody have experience with this?
