Disable OLE DB Services

There are two ways to disable OLE DB services:

• Edit the registry entry [HKEY_CLASSES_ROOT\CLSID\{0D7893B6-1D54-4a22-8D40-AF2FF6B1955F}] and use one of the following values that disables the service(s) as needed:

  Services enabled	Value in connection string
  All services (the default)	0xffffffff
  All services except pooling	0xfffffffe
  All services except pooling and auto-enlistment	0xfffffffc
  All services except client cursor	0xfffffffb
  All services except client cursor and pooling	0xfffffffa
  No services	0x00000000

• For ADO-based applications, add one of the following strings to the connection string:

  Services enabled	Value in connection string
  All services (the default)	"OLE DB Services = -1;"
  All services except pooling	"OLE DB Services = -2;"
  All services except pooling and auto-enlistment	"OLE DB Services = -4;"
  All services except client cursor	"OLE DB Services = -5;"
  All services except client cursor and pooling	"OLE DB Services = -6;"
  No services	"OLE DB Services = 0;"
