I am running Retrospect Express 6.5 at two client sites, both use Windows XP Pro SP2 with all current updates. Both have LANs, are running Norton Internet Security, and need to back up several volumes on disparate computers within the LANs to a central PC (not a server).
At one site, when I run a backup manually, it works fine. When it runs nightly, I get an "insufficient permissions" error (-1017) when trying to access files on a laptop on the network. The laptop is up and running 7x24. Hibernation is off, as is standby.
At the other site, after I installed Retrospect Express, it worked fine manually. The first time it ran automatically, and every time after that, it stopped when trying to access a remote PC on the LAN and asked for a user name and password. The PC is not password protected, and neither is the folder that is shared. I uninstalled Retrospect and reinstaleld it with the exact same results. It worked the first time and never after that. None of the PCs on that network sleep, either.
