Provide more information
1) Server configuration in more detail .. dd-wrt ? OpenVPN uses certificate or static key ?
2) Client configuration in more detail ..  located in China or HK ? OpenVPN client version ?
etc..

At the client configuration file,
......
# client's local DHCP server packets get routed
# through the tunnel.  Solution: make sure
# client's local DHCP server is reachable via
# a more specific route than the default route
# of 0.0.0.0/0.0.0.0.
;push "redirect-gateway"   <= this may be the possible reason, remove the ";" and try again .......

You can also check at the server side for any similar configuration (dd-wrt as server has and yet not sure for OpenVPN as server) to re-direct the default gateway for ALL clients so that you do not need to set the configuration at all clients one by one..

After connection, first check if you can ping the server IP properly.

Then check if you can ping 8.8.8.8 manually at the client side.

Post the result..

Suggest you can simply buy a second hand Broadcom-based router (e.g. LINKSYS WRT54g, buffalo WHR54GS <= around HKD40 - HKD100) and flash it with proper DD-WRT firmware as OpenVPN server.   

The below is the configuration steps that had been tested

More looks like to be a configuration issue at server side and yet I never use WinXP/OpenVPN as VPN server.
Leave it to other cHing who has experience on WinXP/OpenVPN as VPN server who can sort out any idea on your case.
