I am manager of a programming unit. We outsource our systems vendor support. When outsourced vendor installed and tried to run Backup Exec on one of my high end NT4.0 workstations, SP5, the backup hung, and technician assumed operating system was locked up when it did not respond to control>alt>delete to bring up task master. So he pushed button and turned off. When machine would not reboot, he said it was just coincidental. He says system has a bad hard drive. Just coincidental? Are there known issues with this type of problem? Any suggestions on resolution before he moves on to another high end workstation to do the same thing, please? Same company has been unable to resolve our Backup exec issues on a couple of my Novell servers, but they haven't blown anything out of the water until now. I would appreciate any suggestions. Thanks. kz
