steveot, thanks for your answer. I finished the step you mentioned and confirmed that remote agent service was installed and started; however, I was wondering what do I need to do on the backup server to link between the server and the workstation? The reason I asked is when I reinstall win xp pro on the new hard drive of this workstation, I rename this workstation as the same name as before; therefore, the backup job I set before already contains the name of this workstation. I tried to re-configure the backup job, but it kept gave me logon account used to run backup the username and password not match. So, I was wondering how does Backup Exec detect there is a new workstation joined in the group? Also, I suspect the name of the workstation in the current backup job might not be the same as this workstation.
