Server Service disappered

Hello All
Last night in the process of setting up DSL I added a network card rebooted connected DSL modem to the network not realizing that I had not configured Routing and remote access to enable the seperate subnet and to make a long story short upon rebooting the Server I ended up with 2 DHCP servers mine and my provider and an event error. I can not even tell you what the error is due to the server not even booting properly. I had imaged the entire drive 2 weeks ago and this what I’m usingnow. I tried to restore the system state in directory restore but it would not let me log on with this password. any help would be greatly appreciated
