SYMPTOMS

A Distributed Component Object Model (DCOM) method call may return the value RPC_E_DISCONNECTED, or error 0x80010108:

The object invoked has disconnected from its clients.

This error usually occurs when one of the following conditions is met:

The server process calls the CoDisconnectObject function.
The server process ends (terminates).
No network communication is possible between the client and server computer for six minutes or more.

If none of these conditions is true, and you receive the above-mentioned error message, the error may be the result of a vulnerability in the Remote Procedure Call Server Service (RPCSS).

This problem can occur when a single-threaded apartment (STA) does not properly process messages in one or more COM applications. An STA thread should always check the message queue and dispatch messages. For additional information, click the article numbers below to view the articles in the Microsoft Knowledge Base:

INFO: Do Not Make Blocking Calls from an STA Component

RPCSS implements the DCOM garbage collection mechanism for all COM applications that run on the local computer. If a local COM application has an STA that is not processing messages, it can affect RPCSS in such a way that it does not properly perform garbage collection. As a result, a "bad" STA application can cause RPC_E_DISCONNECTED errors for any COM applications on the same computer.
