Do you have DHCP installed in 2k3 Advanced Server? If you do, do you have the scope setup properly?
On your workstations, do they have the power management settings turned off in device manager under the NIC "allow the computer to turn this connection off when not in use" ( or something similar )?
There is also a registry hack to stop windows server from disconnecting "inactive" connections ( i.e. mapped drives ) but I will have to look that up.
I would look at the first two options I gave you before doing any registry edits.
I would also caution you about any registry edits without backing it up first.
