The power went out all of a sudden and when we tried to restart everything when it came back on - our server can't be assigned an IP? We got an error stating that the IP for the server was already in use by another system. We then shut down all systems and restarted the server but then for some reason the server was assigned an IP but no one could connect to it - after restarting the server after setting it to have a dynamically assigned ip - the server now has no ip - just 0.0.0.0 - running an ipconfig/renew or ipconfig /release has no effect.. what should we do!!

==============================
OK the server somehow got the ip and only one pc on teh network can access it - however other pcs can't even ping it for some strange reason. Infact one PC which I'm trying desperately to put on the domain gives me a cannot find domain controller error. Plus when I ran an ip config on the other pcs they show a 'media disconnected' on the ipconfig even though they all have ips set up...... whats happening here?
