Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

It would be great if you would have given the IP address information for these machines and would have let us know the communication flow that occurs between these machines.
The output that you pasted shows that the system's are configured to use "Auto Negotiation" which according to me is the reason behind the slowness. If you could hard code them to use 1 gig speed then it will work fine and when they are communicating with 10/100 base machine the speed will automatically come down to match their speed.
It appears to me that as of now the are communicating using 10/100 base speed by default.
What is the speed of your server's network adapter. If it is a gigbit adapter then yes there is a possibility of network card issue on your desktop. Because from the output you pasted your Desktop has got a gigabit adapter and your laptop has got base 100 full duplex adapter. So if laptop is able to transfer files quickly to your server and not to your desktop then there can be an issue with desktop's NIC.
Could you please let us know what are the OSs installed on these three machines (server, laptop and your desktop)
I will try removing everything that is 10/100 (laptop and ISP router) and see what speeds I get from my lads pc (gigabit, windows) although the 8 port hub should be able to handle mixed speeds.
The server is debian setup with ssh and samba and headless, and yes its a gigabit builtin adapter
The desktop is Ubuntu 10.10
And the laptop is Windows vista.
I think a couple of other things I will check are:
swap network cable from the laptop to the desktop to test the cable,
boot from a clean install of debian on the desktop, just to be sure its not software related as the ubuntu has had numerious updates and things installed and removed over time.
