"Access Denied" When You Run AT Command on Remote Computer

MORE INFORMATION

Assume a user issues an AT command on a remote computer. For example, from computer A, UserA issues the command

   <AT \\computerB 18:00 /interactive "notepad">
				

This has the following two results:

1. ComputerA will try to establish an IPC$ connection to ComputerB, using the account UserA. The Server Message Block (SMB) command is <C session setup & X, and C tree connect & X, Share = \\computerB\IPC$>. UserA must have administrative privileges, otherwise the attempt results in an "access denied" error.
2. Schedule will start up on ComputerB using the account you specified with the Schedule service in the Services tool in Control Panel. By default, it uses the System account.
