Can't ping default gateway

I am a network admin for a small school network with two servers.
Server1 is W2000 and is DC for domain has Exchange on it. Server2 is a
file server, application server with IIS and ASP.NET and Streaming
Media server. Server2 is replacing another server, Server3, just
recently taken offline. Server2 had no problems with original IP
address, but IP address recently changed to be that of Server3. After
IP change, Server2 can ping everything except the default gateway, and
thus cannot access anything outside the network.
Any ideas?

Hi,

Can you check that you assigned the right subnet mask and IP address range
to your computer.

Another thing to check is ARP table on your server that can't ping the
gateway. After you try to ping it run this on the computer

arp -a

Now check if you see IP address and MAC address of your gateway in the list.

Another test to do. Can you ping the server from your gateway.
