I need help resetting my admin password I screwed up and plugged in a key board that the caps lock didn't light up and I typed a password twice that now it doen't let me in because I may have misspelled the password when I originally entered it with the defunct keyboard... I know I'm an idiot... here's my info if some one could help me I'd be grateful. Model DS-7616NI-E2/8P Serial number# 568524278 Also I need to know if any of the jumper pins right behind the lan port on the motherboard are supposed to be jumpers? I ask because there was a loose jumper in the unit when I opened it and its the only area with pins. Hope someone can help me out.
