Network Connection "Failed Error S01"

I've been getting this error message every time my Premiere XL4 tries to connect early in the morning. However, when I manually try to connect, it works fine. I installed a network switch a couple weeks ago, but we went out of town right after that, and it was fine while we we're gone. Seemed to have started this week. I'm having no other problems with the other devices on the switch. For the time being, I'm just manually connecting every other day or so. Any ideas on what might be wrong? Just tried again and saw this message...
