Client receives "Access Denied" result when connecting to a decoupled provider

This article has been archived. It is offered "as is" and will no longer be updated.
When all the following conditions are true, clients connected at the Identify level receive an "Access Denied" result for each subsequent call:
  • You create a program that includes a decoupled provider.
  • The decoupled provider stops responding.
  • You restart the provider.
When the .NET application unexpectedly quits, the .NET Framework cannot call the Unregister() function for the decoupled provider. Therefore, the decoupled provider registration persists. When the client tries to subscribe to the events, it receives a remote procedure call (RPC) error ("RPC Server Unavailable"), and then registration fails with an "Access Denied" result.
