Deadline command error

After I updated Deadline 10.4, I’m having strange problems with Deadlinecommand.

We use DeadlineCommand to stop Worker when the user login. It always worked very well. But after the update some machines perform the command and others not.

The command I execute is Deadlinecommand Remotecontrol %Computername% Stopslave.

I went with a normal user and executed at the Windows Prompt. The message I have is as follows:

Error: Specified argument was out of range of valid values. (Parameter ‘port’) (System.ArgumentOutofRangeException)

I know it may have something to do with permissions, because if I log in with my administrator account the command is successfully executed. But that doesn’t explain because some normal user accounts can stop the Worker and others not.

Can anyone help me?
