Disk Threshold error

[briandking]

I set a task for a disk threshold to run every 4 huors. 4 machines continue to say running, 1 says complete. But the error message below for all of them says "Could not set the disk threshold, the agent did not accept the request" Stumped, able to send trap test from the servers. The account being used is a regular domain user but a local admin on the CMS box.

I saw a thread about possible trust issues, but I am not convinced that is the problem.
