Message Processing Details

Before processing the methods that are listed in the following sections, the server SHOULD obtain identity and authorization information about the client from the underlying DCOM or RPC runtime. The server does this in order to verify that the client has sufficient permissions to create, modify, or delete the object as appropriate. These methods SHOULD impose an authorization policy decision before performing the function. The suggested minimum requirement is that the caller has permission to create, modify, or delete the object as appropriate.<70>

If any method is called before the server returns success from either the IVdsService::IsServiceReady (Opnum 3) method or the IVdsService::WaitForServiceReady (Opnum 4) method, the VDS_E_INITIALIZED_FAILED value is returned.

If parameter validation fails, the server MUST immediately fail the operation, returning a vendor-specific error as its response to the client.
