Hans,
could it be that there is a proxy or a firewall in between you and the
target Web Service?
Just a thought ...

Hello Hans,
This error is typical when connecting through a proxy server. You need to
supply your client (the program consuming the web service) with the proper
settings. You can do this either programmatically or through
machine.config.
For a detailed description of how you can correct this problem, see the
following Microsoft Knowledge Base article.

http://support.microsoft.com/support/kb/articles/q318/1/40.asp
I hope this helps.

SYMPTOMS
========
When you use a .NET client to consume a Web service through an HTTP proxy
server, you may receive the following error message:
The underlying connection was closed: The remote name could not be
resolved.
CAUSE
=====
An HTTP proxy server exists between the Web service and the .NET client,
and the
proper proxy settings have not been configured.
RESOLUTION
==========
To resolve this problem, supply the proper proxy configuration settings to
the
.NET client.
MORE INFORMATION
================
The following are the default settings in the Machine.config file:
<configuration>
<system.net>
<defaultProxy>
<proxy
usesystemdefault = "true"
/>
</defaultProxy>
</system.net>
</configuration>
If the default settings do not automatically detect the appropriate proxy
server
settings, you can change the [**at*(default settings or proxy server
settings?)]
settings explicity in the Machine.config or Web.config files, or you can
change
the settings programmatically.
The settings for the Machine.config or Web.config files are as follows:
<configuration>
<system.net>
<defaultProxy>
<proxy
usesystemdefault = "false"
proxyaddress="http://proxyserver";
bypassonlocal="true"
/>
</defaultProxy>
</system.net>
</configuration>
To change the settings programmatically by using a WebProxy object, use the
following sample code:
Using System.Net;
com.someserver.somewebservice.someclass MyWebServiceClass = new
com.someserver.somewebservice.someclass();
IWebProxy proxyObject = new WebProxy("http://myproxyserver:80";, true);
MyWebServiceClass.Proxy = proxyObject;
MyWebServiceClass.MyWebMethod();
