UDL files will not open

I have a costumer with a LOB running in the native Microsoft Data Access service (please notice that this is native to Windows Server and has nothing to do with Microsoft Office Access)  
The application has  a databasefile called PROGRAM.UDL.
When double clicking this file NOTHING happens!
I can confirm that the file type is associated with "Microsoft Data Access - OLE DB Core Services"

When i duble click a similar file on another server SERVER2, it opens up correctly showing Data Link Properties. This is normal behavior.

Any ideas? :-)

Try re-setting the default application for the UDL extension.
Right click on the UDL file & choose "open with". Initially set it to notepad, and tick the "Always use selected program: option. Verify that double-clicking now opens up the file in Notepad, then repeat the process and re-set it back to "OLE DB core services", again ticking the "Always use" option.

Hi Chev

Have tried - does not help.
pt I am trying to reinstall Server 2003 SP2.
This could be a problem with the OLEdb32.dll
Did you try re-registering that dll?

Hi Chev

How do I re-registre a DLL?
from a cmd prompt run regsvr32 with the full path to the dll.

e.g. regsvr32 "C:\Windows\System32\oledb32.dll"
