SECU1075: An error was discovered processing the wsse:Security header

Question

I have designed a console application as a web service client which is able to talk with webservice; however instead of using
a console application, I've written a DLL that is called from a Winform app and  I am getting following error message.
Error message System.Web.Services.Protocols.SoapException: SECU1075: An error was discovered processing the <wsse:Security>
header
   at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response,
Stream responseStream, Boolean asyncCall)   at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
   at ErcotNodalDll.NodalClient.NodalService.MarketTransactions(RequestMessage RequestMessage) in C:\Pb10_Devl\KeyStone\Dark
Angel\Visual Studio\ErcotNodalDll\ErcotNodalDll\Web References\NodalClient\Reference.cs:line 98
   at ErcotNodalDll.Program.submitPayload(String certificate, HeaderType header, RequestType request, PayloadType payload)
in C:\Pb10_Devl\KeyStone\Dark Angel\Visual Studio\ErcotNodalDll\ErcotNodalDll\Class1.cs:line 243
   at ErcotNodalDll.Program.createBidSetData(String[] parms) in C:\Pb10_Devl\KeyStone\Dark Angel\Visual Studio\ErcotNodalDll\ErcotNodalDlA
first chance exception of type 'System.Web.Services.Protocols.SoapException' occurred in System.Web.Services.dll
I'm told the problem is that the DLL can not find the policycache.config file thus doesn't know how to handle security for the
html.
Anybody know what I need to do to call the webservice
from DLL instead of console application?

You use WSE3 and not WCF (which is this forum main focus). One idea is to consider WCF.
Also:
- the client proxy should have a SetPolicy() method which you can use to set the policy
- use Fiddler to check which message the client sends and which one it gets back. Then compare these to a workign client message.
