Hi,
Definitely try the "run in elevate mode" suggestion before you try anything else. If that fails, you need to check for restrictions that Microsoft has coded into the net.exe command. I suspect you may be bumping up against one of these restrictions. For instance, if you try to run the "net group <group name>" on a Windows Member Server, you will get a message that says, "This command can be used only on a Windows Domain Controller." This begs the questions, what are you trying to do with the command, and from what machine are you trying to do it? You may not be able to use that command on the server you are trying to use it from now. I don't recommend putting an Autosys agent on a Domain Controller, so if it's a use of the net.exe command restricted to Domain Controllers, I would suggest pursuing an alternative using Powershell. I've had that happen to me in the past, and I've always found an alternative in Powershell that worked around those restrictions.
