SYMPTOMS

When you install a Component Object Model (COM) server for use within a Microsoft Cluster Server (MSCS) group, COM communication can fail. This problem occurs when both an application and the COM server are running on the same cluster node. In this situation, COM generates an error such as the following when the application attempts to call the COM server:
OLE received a packet with an invalid header. (80010111)

CAUSE

Currently, an application cannot connect to a COM server on the same machine using anything other than the network basic input/output system (NetBIOS) name of the local host.

RESOLUTION

You can work around this problem by placing both the COM server and the requesting application in the same MSCS group and writing the client to assume the COM server is on the local host.

STATUS

Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
