I have installed Backup Exec on several Windows 2003 servers, either versions 9.1 or 9.0. Upon install reboot, a Windows startup error is displayed " A driver or service failed to start." The backup software appears to be functioning properly. After uninstalling Backup Exec, the Windows error is no longer displayed. Unlike other posts related to this error, it is caused by Backup Exec. Anybody have any information on the cause & resolution of this error? Any help would be appreciated as even though I am a reseller & integrator of Veritas products, Veritas offers no support unless a support contract is purchased. I may have to look into competeing product that actually offer support for their reselers.
