Urgent! Local network access and internet access!

I got a complicated problem here
I am a new tech in the company,two days ago we got a power surge due to the lightening.
Our local network was down and our internet access was down too.
Apparently two of our three switches were dead, and I have to replace all the cables on those switches to the working one. Now everybody can get onto the local network.
The internet guy came today and replace the satellite dish unit because we are using wireless T1, and it seems working on his laptop
Here is the problem: when I tried to connect the switch to the internet router, nobody had internet access.  When I connected the server and the user together to the router, the user had both local network access(server access)and internet access,but other users would not have anything,becaue the server was unplugged on the switch. Even I connect another cable between switch and the internet router,it still did not work.
My description might not be that clear, but please help!

          *Was the link led of switch's port up when you connected the router to it? If not, you may need cross-over cable.
           *Can you please explain what you mean by "server and the user"

thanks guys
the led was on when it was connected
server and user means i connected both the server cable and user's cable directly to the router
it is server 2003 standard
The ip has not been changed, and it is a static ip.
the server can only access the internet when i changed its ip address assigned by  DHCP, but nobody will be able to access the files on the server, even though i change the ip manually under server management to whatever i get from DHCP. If the server keeps the static ip, it wont have internet access

Sounds as if something has changed on the router.
What is the LAN side IP address of the router?
How do users optain an IP address, static or DHCP?
