Attempts to call a COM object through the sp_OA
stored procedures may fail with error messages that indicate:
- COM is not initialized or that COM has already been
initialized with a different mode (HRESULT 0x80010106)
- The worker thread may stop responding (hang) in
OLE32!DllMain when called for DLL_THREAD_DETACH processing as the worker thread
The latter problem may also cause SQL Server to stop

Microsoft has confirmed that this
is a problem in Microsoft SQL Server 2000.
This problem was first corrected in Microsoft SQL Server
2000 Service Pack 3.
When you use sp_OA
related stored procedures to call COM objects, SQL Server must
initialize and uninitialize COM on this worker thread by calling CoInitializeEx
. The initialization occurs when the first sp_OA
call is made in a batch, and the uninitialization should occur at
the end of the batch. In some cases, the uninitialization does not occur, and
the worker thread remains initialized for COM calls.
