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:

Also, within an Ethernet network, all network adapters must transmit at the
same speed (i.e. 100/mbs, full duplex) and be connected to a hub/switch
which supports that speed of the network adapters, or otherwise network
communications will be slow and/or unreliable. The network adapters must
also be configured to support the cable type being used.
