System.Runtime.InteropServices.COMException: '(41,4):UserId:'

[curlydonkey]

I am attempting to add a task on a remote machine but the following exception is being raised when I call TaskService.AddTask():

System.Runtime.InteropServices.COMException HResult=0x80070534 Message=(41,4):UserId: Source=<Cannot evaluate the exception source> StackTrace: <Cannot evaluate the exception stack trace>

My code:

var taskService = new TaskService("192.168.129.62", "xxx", "xxx", "xxx"); taskService.AddTask("xxx", QuickTriggerType.Daily, "myprogram.exe");

I have checked and double-checked the credentials I am using for the remote machine.
