A new Update for Windows Server 2003 x64 Edition (KB918980)
Consider the following scenario. You develop an application that calls the IRow::GetColumns function of the Exchange OLE DB provider. The application is installed on a server that is running an x64 version of Microsoft Windows Server 2003 Service Pack 1 (SP1). In this scenario, the IRow::GetColumns function unexpectedly returns error code 0x80010105. Then, the Store.exe process may crash on the server that is running Microsoft Exchange Server.
