Error when scheduling agent deployment (LANDesk 9.0 SP3)

I've noticed on a lot of machines that I am getting an error when scheduling agent deployment.     We're running LANDesk 9,0 SP3 with LD90-SP3-CP_RC-2012-0605 and LD90-SP3-CP_BASE-2012-0605 installed on the core.

The machines will fail with the result "An internal error occured"  Return code is 1208

If I view the log, the machines say this....

[Exception occured, last attempted operation] RemoteExecute, program = tmp70B1.tmp exception = Object reference not set to an instance of an object.

or

[Exception occured, last attempted operation] RemoteExecute, program = tmp70B1.tmp exception = Could not find file 'C:\Users\zldsk2\AppData\Local\Temp\tmp78B.tmp'.

The agent install actually seems to work fine and the agent is updated but it is not reporting sucessfully when I push out the agent using schedule agent push

Any ideas?
