Systems Management

I have regular patch jobs that are hanging at "Scheduled" as if they begin their first step, but don't further. Every existing and new schedule does this. Same for detect, deploy and detect & deploy. I tried removing the agent and all data from a client and reinstalling, but no change. Lekewise when I rebooted the K1000. They were fine last week. No change to my server settings. I'm checking with our network staff to see if they know of any changes.
