Update the drivers for the network card.

-or-

The problem may be SMB signing or LAN Manager authentication level. In
Windows 2003, default server policy forces all SMB traffic to be digitally
signed which seems to cause a problem in some configurations of XP Pro. In
Local Security Policy (Start > Run > secpol.msc > OK) navigate to security
options (Security settings > Local policies > Security) and try disabling
the option for Microsoft network server:digitally sign
communications(always). Ensure you do this on all machines involved (such
as via a GPO for an OU). Run gpupdate /force on the server after making the
change and do the same on the client machine afterwards.

Security settings that can cause a problem with downlevel client access:
