VPN

Hi all
I'm sorry in advance, behind my English.
Shall I question as to problem with ping, when is client appendant to server, and cannot ping another's client.
Acts about it, that the shall we three practically same VPN (same configuration).
In one’s to us works everything without problems. It makes no odds, what system client has (Windows XP, or Vista). Ping works without any difficulty and all client sees each other.
But on two to us without any difficulty work only client with Windows XP. At the moment of, when has client Windows Vista, so ping anybody and anybody ping his. Sign on to VPN will pass without any difficulty and everything functions just as has. Client ping server and server ping client. But for other there is no and they there is no to him.
I hope, that the am it described enough, join on needed information, perhaps be not good for anything open-type substation.
In advance thank you for help.

Pls do not use automated translators, as they are bad. Rather, try to write your question yourself, in some simple form of English.
