System and User Account Difference with AT Command

• Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0
• Microsoft Windows NT Server versions 3.5, 3.51, 4.0

SUMMARY

Not all processes, applications, and .bat files can be started with the AT command.

MORE INFORMATION

In order to run an interactive application by using the AT command, the application needs to be started with the local system account, and the "Allow service to interact with desktop" check box must be checked. If the Schedule service is set to log on as the local system, scheduled jobs cannot be validated on the network. If you start the schedule service with a user account, jobs can be validated on the network, but they cannot have any user interface, because only the local system has sufficient privileges to allow a service to start a program on the interactive desktop. Unless 16-bit applications have access to the interactive desktop, they most likely not start as they run under Ntvdm. Therefore, you can have network access or interactivity with the system (needed by Ntvdm), but not both.

NOTE: This is by design, for security purposes. You do not want a regular user to be able to schedule a job that would run when the administrator is logged on, and use the administrator's credentials.
