ItAssistant Alerts

Hello,

  I have just started getting a critical alert on one system indicating the server is down.  It has happened for the past two nights, beginning at 5pm, and then another alert is recorded at 6pm saying the system is back up.

  The server is not actually down during this time, but I can't figure out why the alerts just began (no new installations or maintenance done since early Feb when I replaced the system board), what's prompting the alert or how to ignore the alerts without ignoring REAL system down alerts from this server.

  What I did find was some entries in the Event Log that raised my eyebrows.  They are as follows:
