Windows Server 2003 and Network Connection

I have a small server based network with 3 client machines on the network. Each client machine logs into the Active Directory Domain when they log onto their computers. I just added a new laptop to the network. When I plug the laptop into the ethernet wall outlet the laptop does not pick up the netwok connection. Local Area Network is listed as Network Cable Unplugged.

This jack works fine with another laptop that was added to the network months ago. Also, when I have the new laptop at my house the network jack work fine. It only behaves this way when I am at the office and on the Windows 2003 Server network.

try a straight through and then try a cross-over cable, if the jack works and laptop works then your cable is either bad or needs to be a cross over
could be auto negiotiating the spped wrong, in device manager, find ur Network card, properties > advanced try changing the link speed/duplex mode.

do you know if you have a switch or a hub between the wall socket and the 2k3 server?
If you laptop has a wireless adapter disable it when at the office.

Try to plug this laptop to another socket and see if it works. Then check Spped/Duplex settings on 'working' laptop and make the same settings on your bad laptop.

I am going to try everyones advice and divide the points. Do you guys think it could be an issue with Active Directory? Remember, when I connect my old laptop to this netowrk jack it work fine. However, when I connect my NEW laptop to the network jack it gets a network cable unplugged error. This rules out a wiring problem.
It is not related to the Windows server in any way.  Your problem is at the physical network layer.

It very well could be a wiring problem.  If your old laptop has a good network card, it could be more tolerant to bad wiring (eg. running 100Mbit over CAT3 cable), while your new laptop is more sensitive.  Try to bring the speed of your new laptop down to 10 Mbits/half-duplex and see if this links up.  If this works, you have a cabling issue.
