Problem Sharing Files Between PCs

    I have two PCs connected to each other through a Wireless-N Gigabit
    Router (model number WRT310N). One PC is running Windws XP while the
    other is running Windows 7. At this point I do not have, or want,
    Internet connectivity. I would, however, like to call web pages on the
    Windows 7 PC from the Windows XP PC. The Windows 7 PC has php files
    that run C++ files to analyze files supplied by the Windows XP PC and
    I would like to send the results of the analysis back to the XP PC.

    The reason for this is that I am setting up a home based web site that
    allows users to run programs on my Windows 7 PC but I want to keep
    hackers from accessing files on my Windows 7 PC. So the XP will be
    connected directly to the Internet and the Windows 7 PC will only be
    connected to the XP PC.

    I can successfully ping both ways between the Windows 7 PC and XP PC.
    So I fire up FireFox (FF) on the XP PC and type the following in the
    FF URL box.
    [Win7PCIPAddress]/SharedDirectoryOnWin7PC/FileName.hmtl
    The following ensues on the FF browser.
    Looking up searchconduit.com
    Looking up isearch.avg.com
    Firefox can't find the server isearch.avg.com

    The same happens when I replace the Windows 7 PC IP address with the
    Windows 7 PC name.

    I tried to set up a network between the two PCs with the MS network
    wizard on the XP box. It made a setup disk with a single file on it. I
    was supposed to run the setup file on the other PCs that are supposed
    to be on the network but, whe I did, I got the following message.

    Cannot complete the Setwork Setup Wizard,
    An error occurred during the configuration of the network on this
    computer.
    You can configure the network manually.

    I didn't find that message helpful apart from telling me that the
    setup was unsuccessful.

    Any assistance with this problem would be greatly appreciated.
    Peter.

    Your logic is flawed. If you network the two PCs and the web facing one
    gets compromised then the other PC will be reachable because it is
    connected via the network.

    These machines should be in a DMZ and ideally run as VMs.

    Good helpful feedback that. Can't argue with the cut and thrust and
    technically backed up comments.



    Whoops, sorry! Replied to the wrong post.

    I wonder who got the message saying stupid ****?

    Thank you for your reply.

    I'm aiming for the setup described here
    http://en.wikipedia.org/wiki/Demilitarized_zone_%28computing%29 . The
    XP PC is the web layer while the Windows 7 PC is the application
    layer. Both have firewalls. Also, the XP PC is supposed to only
    access files on the shared folder of the Windows 7 PC. Those files
    are less sensitive and call files on unshared folders on the Windows 7
    PC.

    Are VMs not software? Would they not be easier to hack than hardware?

    What protocol?
    http://[Win7PCIPAddress]/SharedDirectoryOnWin7PC/FileName.hmtl

    won't work

    Use:

    file:///[Win7PCIPAddress]/SharedDirectoryOnWin7PC/FileName.hmtl

    BTW --- Didn't you say you had a mapped directory?

    Then it should go like this:

    file:///z:/SharedDirectoryOnWin7PC/FileName.hmtl

    replace "z" with the mapped drive

    Or install a web server.

    Thank you for your reply. I have found that I can do what I want to
    do but only if I share the folder on the Windows 7 PC with Everyone.
    I have set up a network but can only see the network on my XP PC.
    That is on my XP PC I can see bothe the XP PC and the Windows 7 PC.
    However, on the Windows 7 PC I can only see the Windows 7 PC. I have
    successfully set up a workgroup on the Windows 7 PC. It has the same
    name as the network I see on the XP PC but I could not find the
    equivalent of the Network Connection wizard on the Windows 7 PC. So I
    have not managed to set up a network, on the Windows 7 PC that include
    the XP PC. Or at least I may have a network but it can only be seen
    (and seen perfectly) from the XP PC.

    Any assistance with having the network visible on the Windows 7 PC
    would be greatly appreciated.

    Thanks,
    Peter.

    To properly implement a DMZ you need a hardware firewall. It sounds like
    you are using software firewalls on the PCs and if you think a VM is
    easier to hack then it sounds like you are well out of your depth
    because that's not the reason I suggested using them.

    I have many years experience in installing & running web facing servers
    for business clients and I've never had a breach. You are on course to
    be the next spam source and bot net member.

    Go here:

    Control Panel\Network and Internet\Network and Sharing Center\Advanced
    sharing settings

    Turn them all on.

    BTW... It makes things a little easier if the logon creds. are the same
    on each machine.

    Nobody, yet. But I thought you were joking: the OP obviously does'nt know
    much about networking, how would he know the meaning of a DMZ or a VM?

    Indeed. It was meant to prove my point that he doesn't understand what
    he is doing and the implications of getting it wrong.

    Thank you for your reply. The PCs are connected through a Linksys
    router. with an SPI firewall. The available Internet filters are
    - Filter anonymous Internet requests
    - Filter multicast
    - Filter Internet NA redirection
    - Filter Indet (Port 113)

    It can also block the following applications: NDS, ping, gttp, https,
    ftp, pop, imap, nntp, telnet, shmp, tftp and IKE

    I have started reading up on virtual machines and will try to get back
    about that tomorrow.

    Thanks,
    Peter

    Thanks. I had been trying to work through that link before. I make
    sure that both machines have the same workgroup. I also have the
    right advanced sharing settings. But I can't go into Network in
    Windows 7. The Windows Explorer window on has > Computer > but not >
    Network >

    Thanks,
    Peter.

    I looked at my first message and saw that I neglected to mention that
    the XP PC is supposed to be in the DMZ while the Windows 7 PC is
    behind a router. I am trying to set up a DMZ with the web layer
    connected to the Internet and the application layer accessible only
    from the web layer through a type of filter so that it cannot have
    direct access from the Internet. I have ZoneAlarm on both PCs and the
    two PC are connected through a LinkSys router. I am on a steep
    learning curve which is why I'm here.

    Thanks,
    Peter.
