Power Outage caused server crash

Question

A breaker flipped and caused both our dhcp and zenworks server to go offline. My main concern right now is getting the internet back up and running. I logged into Sles and we're running oes2. I don't know if I need to restart a service or what, but the server is displaying that there is a log file for viewing I assume? Any help is greatly appreciated as I can't solve this problem on my own.
Thanks,
Ryan

Good to know where the log file is, I am so accustomed to windows. I have always wanted to learn linux so I guess here's my chance.
some additional tips:
One file I also always check after (re)booting a server is the /var/log/boot.msg. The last lines normally show which services were skipped (normal if there is nothing to do or configured for a service) or failed (which is a first indicator if " stuff" isn't working after bootup).
To get the last lines of that file, use the tail command;
#tail /var/log/boot.msg
Another usefull function of that tail command, is to a get a realtime/feed on a file, like the /var/log/messages;
#tail -f /var/log/messages
Or you can combine it with grep to only show lines with a specific content, like messages given by dhcpd;
#tail -f /var/log/messages|grep dhcpd
Before restarting a service, it's often good to check the current state of a service;
#service [servicename] status
(the service command is the same as using rc[servicename] [action], I find it a more logical way to handle services)
The great thing about Linux is that you can do most things using a ssh console connection. It just takes a little time and practice finding all the (often built in) tools you need/prefer.
