I think I can help. I ran into this before. After the advent of Internet Explorer 4 or so, it changes/removes the Scheduler service. At the minimum it sets it to permanently run under the "System" account. Furthermore, it can not be changed to run under another account as most services can. This was all due as I said to Internet Explorer enhancements.. To resolve these issues Microsoft ha provided you with the "Scheduler" that is in Windows Explorer. Just start Windows Explorer and look for the "Scheduler" in the left window pane. You then can schedule any file to run under a particular username. You get these errors because the System Account does not have the needed permissions to access most if not all drives, shares and resources. Email me if you need help..
