mapping network drives in VPC to my desktop

    Here is my problem. I can only run VPN in 32 bit mode. I have MS VPC 07
    running XP32 on my XP64 system. I map network drives (say "X: Y: or Z:" in my
    XP32 as usual, but I need to access those drives on my XP64 system. Problem
    is that my XP64 can't "see" these drives at all. I am wondering if there is
    in fact no way for this to work. As a linux user, mounting drives etc., it
    seems to me that you should be able to do this, but in windows I can't figure
    it out. Is it possible to do this, and if so, how do I do it?

    Do you mean mapping drives which are accessed from the VPN guest on a
    remote host via VPN??? In that case most certainly it won't work
    because VPN usually by itself (depends on type of VPN) will block all
    other network accesses on the VPN guest as long as the tunnel is up.

    Is machine visible for host OS ?

    I bet it is matter of proper network setting of guest,
    but I am not familiar with it.
    Supposing you know you should not use NAT.

    does have running netbios services and opened ports ?
    incoming UDP 137 + 138, TCP 139
    maybe also 135, not sure.

    try install simple http server, if able to reach it,
    e.g my favorite abyss by Aprelium.

    I am not sure I understood you correctly. If I am simply reiterating what
    you said, then
    my apologies, but the I am not up on the proper vernacular and lingo.

    I have VPN running on my virtual pc and have mapped network drives there
    that show
    up under "network drives". But I want to be able to see those or map then to
    my
    real computer (host I presume). It seems to me that you should be able to do
    this,
    but are you saying that somehow VPN is not allowing for me to map them?

    Cheers
    Paul

    As I understand you the situation is like this:
    - You have a virtual machine running WinXP
    - This XP guest has VPN software running (Cisco or AT&T or what?)
    - With VPN software a connection has been made to a remote server
    - While the VPN tunnel is up you see shares on the remote server
    which are mapped to drive letters on the guest
    - Now you want to re-share these mapped shares as new shares so they
    will be available also on the host?

    This will not work, in fact even if there was no VPN involved Windows
    would not allow you to first map a drive letter to a server share and
    then share that drive letter out for a third PC to map a drive letter
    on its own against it.

    But with a VPN tunnel active you will probably see that the entire PC
    where the tunnel is active is isolated from the local network
    neighborhood so you cannot even see shares on other PC:s in the same
    local network until you close the tunnel.
    This behaviour might depend on the particular VPN software you use,
    but I know for a fact that the Cisco VPN works this way because I have
    been a Cisco user for many years. Whenever my laptop hooks up the VPN
    tunnel it disappears from the local network. All connections I might
    have established to other local PC:s via the LAN completely
    disappear...

    Did file sharing between the guest machine and the host work before you
    installed the VPN client (or did you not try it then)?

    Have you tried sharing folders rather than drives?

    Thanks Bo.

    Yes you have completely understood my situation. I am using Cisco. This is
    not terrible news, but it is disappointing. VPN doesnt run on xp64 as you
    probably
    know, so the VPC was helpful in that regard. But I need to manipulate a large
    number of files using software installed on the xp64 machine. Copying files
    back and forth is not productive...so I'll have to install the software
    suite again
    on the virtual machine, which is a pain plus I only have a license to
    install the
    software on two machines, so I'd be wasting both installations on one
    machine...

    I use Vista64 Home Premium SP1 as host, running VPC2007 SP1.
    I run Win2000 as guest,
    with AT&T VPN client (v6.9, 32b only) to connect to my job.

    I have set a bunch of mapped network drives on guest:

    remote systems from job, seamlessly accessible through VPN
    and
    shared folder(s) from host, set as R/W in VM config
    ( VM has to be running when set this.)

    If I need documents from a job accessible in host,
    I simply copy it ( within guest OS )
    from remote network folder to host network folder.

    Then it is placed in host disk
    and both host and guest have access to it.

    Note that the OP wants to use his guest to establish a VPN tunnel
    (using Cisco VPN) to the remote server. Then he wants to map remote
    server shares to drive letters in the guest (this is possible).
    Then he wants to share these drive letters (or folders within) in the
    guest in such a way that they will be accessible from the *host*.
    Finally he wants to use software on the host to work with the files on
    the remote server using this double mapping scheme.

    AFIK this double sharing is not even possible if there was no VPN
    involved, but with Cisco VPN the guest will be totally disconnected
    from the local network as long as the tunnel to the remote server is
    active (to protect the remote server from illegal accesses, I
    believe).

    So the bottom line is that the VPN system will disable all networking
    from the guest except the tunnel itself and so he will have no access
    to the guest from the host.

    Other VPN software may work differently in regard to the network
    isolation, for example Microsoft PPTP tunneling does not do this. But
    still the double sharing is not possible, I believe.

    I see, I missed it. So do I think double sharing is not possible.

    I suppose VPC shared folders bypass common Windows networking.

    I think that it possibly does too, but the shared folders by VPC
    design is a feature to share a *host* folder over to the guest and not
    the other direction. In this case it would not help the OP except if
    he was willing to first (in the guest) copy the files from the remote
    server into the shared folder and then operate on them in the host and
    then finally in the guest copy them back.
    But he said that there was a large number of files involved so he did
    not fancy this copy-modify-copy process.
    Installing the processing software in the guest will solve the problem
    but costs another s/w license....

    Yes, the sheer number of files involved makes the copying back and forth
    unattractive. Of course
    copying files back and forth is not an issue.

    In any case, I was told there may not be a licensing issue with the VM
    afterall.

    Thanks all for their knowledgeable input.
