Computer networks

Hello!
There is a small network, 10 computers. The problem computer connects to all the others from this network, except for one. Ping to it, from a problem computer does not go. Otherwise, everything works. I changed the working group, turned off the firewall, the "Server" and "Workstation" services are working. Problem computer on WinXP, the second on Win7.
Connected like this: Computer 1 (problem) - switch 1 - switch 2 - computer 2.
Please help me figure out what the problem could be.
Problem computer:

Microsoft Windows XP [Версия 5.1.2600]
(С) Корпорация Майкрософт, 1985-2001.

firewall\antivirus\windows network access setting (in my opinion it was somewhere in the adapter properties).

Disable the built-in firewall on W7. If there is an antivirus, such as Kaspersky, then disable it for verification.
