Networking problems

Hello all,
I'm having a weird problem with my home network (ie a desktop and laptop hooked up via a cross-over cable). When I transfer files from the desktop to the laptop the speeds are quite nice (4.5 MB/sec), however when I try to send files from the laptop to the desktop the transfers are increadibly slow (12 KB/sec). I've tried fiddling with settings, updating the drivers I can't seem to improve the speed. I'm baffled why the up and down speeds would be different.

Here is the system information:
Desktop:
celeron 1.7ghz
256 mb
aopen ax45-v with onboard lan Realtek rtl8136/810x
lucent winmodem
sb live!
Geforce 3 (original not TI)
2 hds, 1 cdrw, 1 cd

Laptop:
this is a standard Toshiba sattelite 1115-s103
the Nic is also a realtek rtl8139/810x

any help would be greatly appreciated.

Thanks
Brent

Whoops, I thought I put that in my post. Oh well. The desktop has win 98 se and the laptop has win xp home sp1
