Test Connection failed while exporting from Access to SQL SErver 2008 R2

Hi,

I am importing data from access to SQL SErver 2008 R2 using IMPORT / Export Wizard.

But as soon as I select Source as Access and enter my admin username and password, I get following error message :

Microsoft Data Link Error :

Test Connection failed because of an error in initializing provider. Cannot start your application. The workgroup information file is missing or opened exclusively by another user.

Any inputs ?

Thanks,
