Hi, I'm trying to create, modify and get a DNS Resource Record using the DNS Provider, yet every time I do it, I get the following message: Couldn't create instance of Microsoft.Provisioning.Providers.DnsResourceRecord_type Resource Record The XML I am using is something like this for GetResourceRecord: 10.1.1.1 Administrator xxxxx myDomain.com a www The setup I have at the moment is ( all seperate machines ): Webservice API running on Windows Server 2003. MPS Engine running on Windows Server 2000. DNS server running on Windows Server 2003 with MPS DNS Client. I can create a DNSZone without problems, so the security & authorization seems to be okay, it is only creating, modifying and retrieve DNS Resource Records that is causing problems. Thanks in advance for any help. Sieu
