Can connect to network on Lan but dont have access to internet or Mail

Hello,

I am at work and up to this point I have never had an issue connecting to the internet through our network LAN connection. I also have access to the office WIFI, but need resources such as the print that I can only get through the LAN connection.

I can see our office network and all the computer that are attached and our office adminstrated can see my computer when I am attached through LAN, but I cant access the internet or get mail.

I have tryed renewing the DHCP IP address and dont know what other options I can do to help with this issue. If anyone can shed light on this it would so much be apperciated.
