Bad news, this is a bug in 10.2.0.1.

Check Metalink document 361325.1 (hope you have access)!

Maybe you'll just have to grant additional privileges but it is possible that you'll need to apply the 10.2.0.3 patch set

I hit the same issue. Closed the command prompt.Opened one with Administrator Rights - Open CMD as Administrator.

That's it. This solved all the issues I had been facing.

If you have saved the SQLLOADER/SQLPLUS scripts as a batch file, then submit/open the batch file as administrator .

Hope this helps.
