‘Microsoft.Crm.WebServices.Crm2007.MultipleOrganizationSoapHeaderAuthenticationProvider’ doest not exist


Got this error while running a custom aspx page within the isv folder of CRM 4.0. To resolve the issue we need to add Microsoft.Crm.WebServices.dll either to our application or to the gac of the server.

Microsoft.Crm.WebServices.dll – It could be found at following location C:\Program Files\Microsoft Dynamics CRM\Setup

Check this info as well
