I'll try to do that. The problem is that the error is only occuring in a
test site located far in Germany!
In the meantime here is some usefule code:

thx

   try
   {
    // initialize the state machine
    remoteObjects = this.CreateRemoteObject();
    if((remoteObjects.adminObject == null)||(remoteObjects.sponsorObject ==
null))
     return false;

    //Activate the renewal mechanism
    instanceSponsor = (InstanceSponsor)remoteObjects.sponsorObject;
    serverLease =
(ILease)RemotingServices.GetLifetimeService((MarshalByRefObject)remoteObject
s.adminObject);
    serverLease.Register((ISponsor)instanceSponsor);
   }
   catch(Exception e)
   {
    errorNumber = (long)ErrorCollection.CreateCredential_CreateRemoteObject;
    errorDescription = e.Message;
   }

private RemoteObjects CreateRemoteObject()
{
 try
 {
  //setting up the transfer channel and creating the object
  TcpClientChannel clientChannel = new TcpClientChannel("", new
BinaryClientFormatterSinkProvider());
  channel = clientChannel as IChannel;
  ChannelServices.RegisterChannel(channel);

  object[] attrs = {new UrlAttribute(this.serverURL)};
  ObjectHandle oh =
Activator.CreateInstance("SE.Admin.Server","SE.Admin.Server.AdminServer",att
rs);
  object sponsorObj =
Activator.GetObject(typeof(SE.Admin.Server.InstanceSponsor),
this.sponsorURL);
  object adminObj = oh.Unwrap();

  return new RemoteObjects(adminObj, sponsorObj);
 }
 catch(Exception e)
 {
  Debug.WriteLine(e.ToString());
  throw e;
 }
}
