    One way access only

    All three PCs in our set up run Win XP Home edition SP2.

    The problem
    We had two PCs, let's call them A and B, happily networked together connecting to the internet through a router and able to see each other's files. A has a printer and B can print to it.

    Now we have added a third PC, call it C. (My son has moved back home.) Plugged C in to the router. C also has a printer.

    C can access the internet and files and folders on A and B, but A and B are totally unable to access C. It shows in the MSHOME network, but when we try to access it we get the message ' <C's computer name> is not accessible. You might not have permissionto use this network resource. Contact the administrator of this server to find out if you have access permissions. Access is denied.'

    On C, we have set drive C, the My documents folder and the printer to be shared. The sharing and security settings appear to be identical to those on A and B.

    Firewalls:
    A and C are running Zone Alarm with the IP addresses of the other computers (as assigned by the router) all added to the trusted zone. Both have the Windows XP firewall set to off. B is only running the Windows XP firewall, set up to allow networking, and that seems to cause no problem - A and C can see B happily enough.

    Things we have already tried
    1. We have tried running the network set up wizard. After I had run that on my PC (A) I then couldn't access the rest of the network at all, so I remedied that by going back to a system restore point.
    2. We tried running the network trouble shooter. It suggested that C might not have a unique computer name. We were sure that it did but renamed it anyway, to no avail. Undid that by going back to a system restore point. But that leaves my PC (A) showing both of C's names in the MSHOME network, though obviously the PC isn't there twice. Going back to a restore point doesn't remedy that. Other suggestions in the trouble shooter don't seem to have helped either.
    3. Of course we have tried innumerable restarts.
    4. A and B can ping C perfectly well both by its IP address and by its name.
    5. A link to an MS page on a previous post in this board suggested it was important that the Guest account was active - we checked and it is.

    Don't know what else to try! <img src=/S/hairout.gif border=0 alt=hairout width=31 height=23> <img src=/S/help.gif border=0 alt=help width=23 height=15>

    Re: One way access only

    Have you set up any shares, including the printer on the "C" computer?

    Re: One way access only

    I don't use ZoneAlarm but in Sygate's Personal Firewall options, there is a setting to allow browsing of network files and printers and to allow others to share my files and printers. Might there be such a switch in ZoneAlarm?

    Re: One way access only

    Yes - see the para just above the Firewalls heading above. We have right clicked the C drive, and the My Docs folder on computer C, and under Properties -> Sharing we have checked both the boxes for 'Share this folder on the network' and 'Allow network users to change my files'. The 'make this folder private' box is not checked. We have right-clicked the printer and under Properties selected 'Share this printer'. Is that sufficient?

    Re: One way access only

    Well the ZA equivalent is the 'Trusted Zone' settings I mentioned. The settings in ZA on A and C are the same, but A can't access C, though C can access A, so I don't think it's ZA. In fact, turning ZA off didn't cure the problem either.

    Re: One way access only

    Can A and B print though C's printer?
    Can A and B see the file shares on C (i.e. can see but can't access)
    Do you have Norton AV running on C?

    Re: One way access only

    I have never had any luck on sharing "My Documents" accross a network
    I have always shared by the way of Cocuments and settings'username'

    Or better yet, share the hard drive

    Now running HP Pavilion a6528p, with Win7 64 Bit OS.

    Re: One way access only

    We have shared the hard drive and the My Documents folder, but I'll try sharing via Cocuments and settings'username' as well.

    No. Can't use the printer - can't even find the printer actually.

    Can't see the file shares. We can only see the computer name in MSHOME, but can't get further than that.

    We don't have Norton AV running on C. All three PCs are running AVG.

    Tried sharing Cocuments and settings (and restarted at both ends) but still can't do more than see the computer name.

    Re: One way access only

    On computer C can you look at the permissions on the shared folders, and on the shares themselves. (I have no idea how you do this on XP Home, as I use XP Pro.)

    Do you have a username on computer C that is identical to the username you have used when logging in to A and B, with the same password?

    Re: One way access only

    I am not sure either how to look at the permissions themselves.

    I don't have a username on C - only my son does, though he has one on A and B. Is it necessary to? (I only want access to C so that I can use the printer, really. He has a colour printer while I have a mono laser printer.)

    Re: One way access only

    You need a valid username and password on EVERY computer you use, whether that use is an interactive login or a network connection. In some very insecure networks this username may be a guest account that works for everyone.

    Try creating a user account on computer C that has the same username and password as you use on A and B.

    Tried creating a user account on the PC I can't access, same name as on my PC - no luck. <img src=/S/frown.gif border=0 alt=frown width=15 height=15>
