256986 Description of the Microsoft Windows Registry



SYMPTOMS
When you attempt to create a link to an OLE DB datasource by using the Universal Data Link (UDL) wizard on the desktop, the import\export wizard, or the Data Transformation Services (DTS) designer, the available OLE DB providers are not enumerated.



CAUSE
The problem can be caused by a bad entry in the registry at HKEY_CLASSES_ROOT\CLSID. The bad entry may resemble the following (but much longer):

000????????????????????????????????

The entry is easy to find because is the first entry in the key.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

 Start Registry Editor (Regedt32.exe). Locate the following key in the registry:

HKEY_CLASSES_ROOT\CLSID\000<<<<<<<<<<<<<<<<<<<...<<<<<<

NOTE: In this registry key, the &quot;...&quot; represents about 180 boxes. The number of these characters is not important. If you see an entry that resembles this, it is probably the problem entry. On the Edit menu, click Delete, and then click OK. Quit Registry Editor.
