    Laptop can see Desktop but not other way round (SP2)

    Hi all

    Just a quick weird question. I have two machines both on XP SP2 connected to my home Netgear router. Both have software firewalls installed and both have netbios enabled through these 'walls. The weird thing is I can see the desktop pc from the laptop, access shared volumes and do all the usual stuff but when I try to open the laptop from the desktop it errors saying its not accessible and it might not have the permissions to use the network resource/ Network path was not found.

    Am I missing something really obvious here? Both are on the same workgroup and all internally assigned IPs are trusted through the software firewall. This worked previously and I don't remember changing anything that would cause it but perhaps some of the knowledgable peeps out there may see something obviously wrong.

    Cheers

    Neil

    Have you set up any "Shares" on the laptop, so the desktop will something it can look at?

    Yup, shares on both machines.

    Don't know what firewall you're running, but with Sygate Personal Firelwall, there is an option to enable or disable "Network Neighbourhood" settings. I had a similar problem on one of my machines, and this turned out to be the problem. Don't know who switched these settings off (and of course everyone else pleaded <img src=/S/notmyfault.gif border=0 alt=notmyfault width=15 height=15> ), but as soon as I enabled them again, everything was back to normal.

    Have you disabled any services or accounts? Have you added any hardware or software since you last knew it to be working?

    Remember that if you are trying to share the "My Documents" folder you MUST remove the check mark in the properties to make the folder private.

    Sorry guys, triied all of this. Mcafee firewall is set to trust local networks and all shares are active. As for additional hardware only a bluetooth mouse/keyboard so doubtful it would be that. Software is more difficult but I don't believe there is anything that would be changing settings on the network.

    It's really odd this one and I'm totally stuck [img]/forums/images/smilies/sad.gif[/img]

    Thanks for the suggestions so far.

    Re: Laptop can see Desktop but not other way round

    To eliminate the firewall as the problem, try turning tt off on both machines and test again. Also, is the "Guest" account enabled on both machines ? (see <!mskb=300489>Microsoft Knowledge Base Article 300489<!/mskb>.

    Re: Laptop can see Desktop but not other way round

    John, both machines (now) have the guest account enabled and I switched off the firewall on both machines still with no luck. I checked to see if they're on the same workgroup name and they are. Weird thing is I can't seem to ping the laptop from the desktop even with the firewalls off. I guess the hardware firewall would not stop pings on an internal network only from incoming packets?

    If one PC can't ping the other then your problem is definitely NOT related to shares, guest accounts, or any other Windows features. This is a TCP/IP network problem. So I'm going to moved this thread from the Windows XP board to the Networking board.
    <UL><LI>Can you check that both PCs are set to get their IP Address and Gateway from the router.
    <LI>Can you try to ping the Gateway address from both PCs to see if that works.
    <LI>Can you type the command IPCONFIG in a command window on both PCs and let us see the output
    <LI>Check that each PC can ping itself
    <LI>If we still can't see what the problem is then try NETSH DIAG GUI from a command prompt and run the network diagnostic tests[/list]StuartR

    Re: Laptop can see Desktop but not other way round

    Right, answers to all of below (thanks for the continued help btw), both machines had these tests performed with the local software firewall off:

    * Both PCs get their IPs from the DHCP server on the router
    * I can ping the gateway from both PCs
    * Output from both machines IPCONFIG /ALL is attached
    * Both PCs can Ping themselves
    * I can Ping the desktop from the laptop but not the other way round, the only Ping that does not work is from the desktop to the laptop (both machines are wired btw, no wireless (but that doesn't work either))
    * I will wait to try this until you've had a chance to look at the outputs
    * The extra IP on the system is my work VPN connected via the Cisco VPN client however it makes no difference if this is active or not, the problem still happens

    Thanks again

    Very strange. This sounds like a firewall is interfering. Have you ever had any other firewall software installed. We have seen similar problems in the past where ZoneAlarm has been turned off but still prevented connections from working.

    Re: Laptop can see Desktop but not other way round

    No, no other firewall other than Mcafee Personal has ever been used. This is a new problem as I used to be able to connect between the two machines but something (whatever that something may be) has changed. I double checked to ensure the XP SP2 firewall was disabled on both machines, and it is.

    I really don't get this unless something in the networking side of things is missing or has changed in some way. Do I need to have the v6 TCP/IP stack installed on both machines? I have the normal stack installed on both but only on the desktop, can't seem to get it to install on the laptop.

    Can you explain what you mean by "I have the normal stack installed on both but only on the desktop, can't seem to get it to install on the laptop." Have you upgraded one of these PCs to IPV6 networking? What have you been trying to install, and what happens when you try?

    Re: Laptop can see Desktop but not other way round

    Sure, the usual XP TCP/IP stack is installed on both machines, when SP2 was installed it automatically added the v6 stack to both machines. For some reason it's no longer on the laptop (may've been removed when another app was installed but not removed by me) but it's still present on the desktop machine. I've not deliberately installed the v6 stack and not tried to move the network over to that version. However if I try to add the v6 stack back onto the NIC on my laptop it comes up with a weird non-descript error and does not get added.

    I'm not sure if this has anything to do with it.
