Hi all, I have ask this question last week but unfortunately the answer was not able to solve my problem. My server is running on NT platform and with Oracle db. I am using BackUp Exec to backup 3 drives and our Oracle data, a few months ago I decided to select another drive for backup as well, but unfortuntnely the disk do not have enough space so i decided to de-select the last drive that added. Since then I wasn't able to run a good back up... The error msg is "Unable to attach to Oracle, Access is denied". What should i do please....
