I am trying to run an Excel AutoOpen macro using Excel 2002 and Windows XP. When I try to use task scheduler to execute a dos batch command to open the Excel file and have it run the macro code the procedure works fine except for when the machine is under the windows password screen saver mode. I need to run the code at night and leave the machine up and running with the password protection enabled. I get a message of "Not enough system resources to display completely". As soon as you click the OK button the thing runs. Is there a way to stop this error message? I have found that I can run an Access macro that kicks off the same Excel macro and it works OK so I doubt that the problem is a system resource. I would like to avoid the extra Access step if I could to get this to run.
