This sounds like it may be related to issue 3984.

Visit the bugs tab, bugs.contribs.org, and search on "VPN" for more information.

I have never successfully established more than one PPTP VPN from a single NAT'd LAN to a single PPTP server.
From everything I have read, PPTP "uniquely" identifies VPNs based on the public IP address at each end -- so from any network using NAT you will get (at least, I have always gotten) strange behavior any time you have more than one LAN workstation connected to the same remote PPTP server. The last time I researched this, either the second connection would fail, or the first connection would stop working when the second connection was established.
I saw a note from Charlie a while back saying that there are subtleties to PPTP that could allow multiple connections from one NAT'd office to a single Microsoft PPTP server -- but I've never seen it work. Perhaps if you're using a Windows box as the network router, but I haven't seen it work with Netgear, Linksys, Cisco PIX, or Sonicwall routers, nor from a network using a SME server in router-gateway mode - connecting to a remote Windows server (directly or using PPTP "pass-thru") or a remote SME server.
