Windows 2003 advance server looses network connection

After connecting our W2003 Advance Server to our network
I had the following problem. I am not using the server
as a DHCP, I am connecting to a DSL Router with DHCP
enabled, I have the nic set up to automatic ip address
assignment by dhcp. As soon as I plug in the nic cable
to the Linksys dsl router I get a green light on the nic,
indicating connection. After a few moments I get an
error message on the server that the network cable is
unplugged. I tried a different cable and different nic.
Same results. Can someone help trouble shoot this
problem.

it could be hardware issue. check the NIC settings. For more and other information, go to http://howtonetworking.com.
