Please help me out....

My brother reloaded Windows XP on his computer to deal with a Trojan horse virus that had crippled his computer.
NOW he needs the drivers to run his Ethernet controller which is identified in the
CONTROL PANEL\SYSTEM PROPERTIES\HARDWARE\ETHERNET CONTROLLER\DETAILS\
HARDWARE ID'S as:
PCI\VEN_10DE&DEV_01C3&SUBSYS_0C1110DE&REV_C2
PCI\VEN_10DE&DEV_01C3&SUBSYS_0C1110DE
PCI\VEN_10DE&DEV_01C3&CC_020000
PCI\VEN_10DE&DEV_01C3&CC_0200

Compatible IDs are:

PCI\VEN_10DE&DEV_01C3&REV_C2
PCI\VEN_10DE&DEV_01C3
PCI\VEN_10DE&CC_020000
PCI\VEN_10DE&CC_0200
PCI\VEN_10DE
PCI\CC_020000
PCI\CC_0200

He no longer has any software except the Windows XP disks and has asked me to see if I can "find" the drivers for him.
I haven't opened up the PC (it is a desktop pc I'm working on) so I don't know what brand of Ethernet card is installed -
I would rather not make things worse by messing up any of the hardware (I'm not interested in buying him a new
computer ;-P) - so I'm not sure what manufacture to goto for the drivers. ALSO, I am running Windows Vista and don't
have any of my old PC software and drivers due to a house fire,  SO.....Can anyone help? Thanks - Doug
