Network Card Process lock problem

I installed Mageia 2 64 bit from the dual arch. CD about 2 hours ago, and booted back into Windows to check up on things. When I booted back into Mageia I tried installing firefox, and found that it was not connected to the Ethernet. I opened up the connection screen, and told it to connect. It failed to connect, and said that PID 2672 was already using it. There is no process monitor that came installed, so I could not investigate the problem, and I do not know many commands in the terminal. How do I fix this?
