99% of the time when you have 1-way ping, there is a software firewall involved on the one that cannot be pinged (machine B)

*****Most Networking Problems with XP*****

Are caused by Firewalls (either hardware or software)
If you have Zone Alarm, Black ICE Defender etc turn them off! If the problem goes away, you need to reconfigure the firewall. Also Windows XP by default has a built in firewall (ICF) to disable
1.  Open Network Connections (Click Start, click Control Panel, and then double click Network Connections.)
2.  Click the Dial up, LAN or High–Speed Internet connection that you want to protect, and then, under Network Tasks, click Change settings of this connection.
3.  On the Advanced tab, under Internet Connection Firewall, select the following:  Clear the Protect my computer and network by limiting or preventing access to this computer from the Internet check box. This disables the firewall; your computer and network are then vulnerable to intrusions.

99% of the time this is because of a firewall that is blocking comms between the two.
The one that can ping probably has a firewall activated.  disable it and any other firewalls and try again.

I have seen close posts on time but not being so close to saying the exact same thing.
