SDK SOAPLogger throws (401) Unauthorized exception

Hi All,

I'm trying to access our Dynamics 4.0 IFD(?) from Dynamics SDK's SOAPLogger sample but having some troubles. 

I've changed the SOAPLogger's sample code discovery service addresses to work with our old deployment (i.e. now using "http://{0}/MSCRMServices/2007/AD/CrmDiscoveryService.asmx") but everytime the code runs ServiceConfigurationFactory.CreateManagement from GetProxy function I'll get 401 Unauthorized, i.e. I'm denied access. 

Same happens with Authentication sample code as well.

All help would be greatly appreciated.
