Good advice. Regarding the server that was causing trouble: I've dealt with a server that had very similar symptoms. Weeks of troubleshooting that led nowhere resulted in me throwing my hands up and assuming the motherboard itself was just bad and swapping hardware with an available hot spare. Problem solved. Months later after trying to redeploy the original server, I realized the DRAC card was both faulty and misconfigured, causing the aforementioned nightmare. Card removed, problem solved.
