I already setup the Cisco PIX 501 PPTP VPN and work well in client to site access, but I have the problem of ouside VPN client to client access.
Inside LAN:
When user A get PPTP IP is and user B get, HOW CAN I enable user A to access user B through the VPN tunnel. I sure MS Route and Remote Access server can.

I don't think what you want to do is possible as the PIX will not allow traffic out the same interface it came in - ie you are coming in from the outside interface - you cannot route traffic back out the same interface to a different vpn client.  Before you take that as gospel, hopefully someone else can clarify as I have searched for documentation re same but have not come up a definitive answer.

Nodisco is correct. The PIX does not route traffic on the same interface and the two remote clients cannot communicate with each other.

Only way for you to do that would be to setup a RRAS server behind the PIX with a dedicated public IP address, let the clients connect to the RRAS server and let "it" do the routing between clients.
