My server keeps shut down and now wont boot up. It powers up but nothing on the monitor. The hard drive gets power and the nics are firing. This sever is my dhcp, dns & the second domain controller. The other thing is that everyone is still up on the internet even though dhcp is down. I've started to add dhcp & dns to another server (windows 2003) and the primary domain controller is still running in the data center, but I am at a loss why this server wont boot back up.
