Router does not recognize my pc on my network...

edited June 2007 in Science & Tech
I have a Netgear Router that has a laptop & 2 desktop pc's connected to it. For some reason I can't access shared folders on my network. When I log in as admin on the Netgear site, the Netgear Router does not even show one of my desktop pc's. What is the problem here???

Thank you kindly,
Ice

    When you say the Netgear doesn't show one of the PC's, where does it not show it? In DHCP address leases? Does that computer have the Internet?

    Since you only mention file sharing I'm assuming all PC's at least have the Internet. Am I right?

    Regardless of whether your Netgear shows one of the computers, if all PC's have the internet, then all PC's are taking IP addresses from the router and are doing all the communicating they need to. Depending on where you are not seeing one of the PC's in the router, it wouldn't shock me if things were just fine and a little residential router had a glitch.

    Have you run the Network Setup Wizard in Control Panel?

    Do you have Norton Internet Security or some other Internet Security Suite thing on the computer that can't share? Or is it all the computers that can't access network shares?

    Is the network configured correctly?

    Netgear does not show one of my pc's under: Maintenance / Attached Devices...All computers share the same internet and are connected.



    Have you run the Network Setup Wizard in Control Panel? Yes


    Do you have Norton Internet Security or some other Internet Security Suite thing on the computer that can't share? Or is it all the computers that can't access network shares?



    No I do not have NIS, I use AVG Free & Kerio Person Firewall Free Edition. The only pc that can't share / access is the same one not shown on the Netgear Router.

    I thought it was, but I cant say for sure, that's why I came here:bigggrin: seeking some guidance/suggestions.


    Here's the alert I'm getting: \shareddocs is not accessible. You might not have permission to use this network resource. Contact the Administrator of this server to find out if you have access permissions. No network provider accepted the given network path.

    This leads me to believe that one of my pc's is not allowing me to access shared resources, but I dont know why that is, it was working fine when I originally setup the entire network. :confused:

    Yea that error in particular, makes me think you just aren't getting there. If the error was "You do not have permission" I would say you're getting to the share but don't have rights. You are not getting there.

    I wouldn't be too concerned about not seeing a computer in the router. I don't really trust these little residential routers (my Linksys included) to log everything well. Furthermore, it might not be showing because of that firewall.

    I don't know that firewall well. First thing I would do is diable it, and many of them aren't truely shut down even when you disable them. A firewall problem would yield that error.

    I would also say that if you are behind a router, there is no real need for a firewall....unless you are in the habit of bringing home sick computers like some of us. The network setup wizard configures the Windows firewall. That means you now have two firewalls running, which can often make a real problem.

    I have the strong feeling that uninstalling Kerio will suddenly solve all. If you don't want to do that, you need to learn to read the logs and configure that Kerio.

    I was told by a friend that the Netgear Router has dual firewalls...also I was told by someone aiding me with my HJT log that I do not have a firewall installed, hence the reason I downloaded and installed the Kerio Firewall. If my router has "dual" firewalls, is the Kerio Firewall necessary at all?

    Are you saying that one of my other pc's is blocking me, or would it be something on my end? I have full admin rights on my pc, but I dont know how to change it on the pc I'm trying to access?

    1. I'm not sure what dual firewalls means in this case. What is the model of the Netgear? At any rate, hardware firewalls (the Netgear) protect the trusted zone from the internet. I've never seen one that protects trusted computers from each other. Besides, if it did, it would tend to be an all or nothing at all. You have some nodes that can share and one that can't.
    2. When you told me you ran the network wizard, that always turns on the Windows firewall. I don't believe that shows up in HJT.
    3. And if you have the Netgear, you really don't need Keiro or any other firewall as long as you know everything on your side (trusted side) of the Netgear is clean.

    Ice Cream I thought your error said you don't have access. That sounds more like a firewall or networking issue.

    If the error talks about permissions, that is in the security tab of the folder you're trying to share. If you've run the network wizard though, that automatically sets that correctly for the Shared Documents folder.

    I still don't think you're getting to the Shared Folder, and many software firewalls with default settings will block you and produce the access error you described in your first post.

    Okay, can we go from here?

    1. Here's the alert I'm getting: \shareddocs is not accessible. You might not have permission to use this network resource. Contact the Administrator of this server to find out if you have access permissions. No network provider accepted the given network path.

    How do I correct this?

    Icecream,

    Lets go back to basic network troubleshooting:
    1. Kill all firewalls...all including the Windows firewall. It's OK, you're behind the Netgear.
    2. Go to the computer you can't reach. Find out the IP address. Run> cmd> Enter. In the command prompt window type ipconfig /all, then hit Enter. Scroll to the network card you are using (don't know/remember whether the affected computer is wireless or wired but go the that network connection) and find the IP address. Then go to one of the others and ping that IP address. It's the same command prompt process except type "ping 192.168.1.100" but insert the correct IP address in the command and don't type the quotations.
    If you don't receive 4 replies with all the firewalls down, we've got a more basic problem. If you do get 4 replies with the firewalls down, see if you can see the Shared Folder.

    Okay with all firewalls shut down, I sent 4 packets and received 0. What now?

    More basics. We've got to be able to ping the IP address of the problem computer before we can look at anything else. Go back to my post 12 above the describes how to get IP address info. Do that on one of the computers that networks, and on the one that doesn't. For the network card you are using to connect show the following for both computers:

    DHCP enabled?
    IP address =
    Default gateway =
    DHCP server =
  • edited May 2007
    Problem PC:
    DHCP enabled? Yes
    IP address = 192.168.0.4
    Default gateway = 192.168.0.1
    DHCP server = 192.168.0.1



    PC I'm trying to reach:
    DHCP enabled? Yes
    IP address = 192.168.2.2
    Default gateway = 192.168.2.1
    DHCP server = 192.168.2.1


    When I ping IP Address of problem pc, from pc I'm trying to reach, everything is fine (no packet loss). But, when I ping IP Address of pc I'm trying to reach, from problem pc, this is the information received:

    Pinging 192.168.2.2 with 32 bytes of data:

    Request timed out.
    Request timed out.
    Request timed out.
    Request timed out.

    Ping statistics for 192.168.2.2:

    OK RoadRunner...there's the problem. You have two DHCP servers. Usually that's because you have a VoIP box that has DHCP also. Is that the case? Maybe somewhere else.

    The first three numbers (octets) in the IP address must be identical. That means 192.168.2.2 will not network with 192.168.0.4. Another way to tell what's going on is that there are two separate gateways. The gateways should be identical...in your situation it should be the address of your router. The only ways that could be true is if: 1) there are two DHCP servers, 192.168.2.1 and 192.168.0.1, or 2) there are static IP addresses in one computer. And since the data you just posted says that both computers are set for DHCP (meaning no static IP settings), that means there are two different DHCP servers there.
    1. What else is on this network?
    2. What is the model number of the Netgear?
    3. If you type the addresses of those two gateways in a browser, with one address you should get to the Netgear. With the other gateway address you should probably find the other gateway that is handing out IP addresses from a different subnet. When you find that out, take that out of the network, then reboot the PC getting its IP address from that device. It should then be on the network.
    4. If I'm right about that, you can put that device back on the network, just don't have anything plugged into that other device's LAN ports where it's handing out its own addresses.

    Okay, I have 3 pc's total that I want to network. I now have 2 of the pc's (both are desktops) sharing. The third pc, which is my laptop (wireless connection), is linked from the same netgear router going into a wireless Belkin router. The laptop can access the internet, but does not recognize my 2 desktop pc's. Is there a way to make all 3 share? Thank you so much for your patience with this issue. We're 2/3 of the way there. :D

    Yea, I'll bet you have a cable coming out of the Netgear going into the WAN port (sometimes called "Internet" on some routers) of the Belkin wireless. Just move that cable to one of the LAN ports of the Belkin wireless. That will take the Belkin's DHCP out of the mix and everything will get it's address from the Netgear. After you make the change, release and renew (repair) the wireless card on the wireless laptop. If you don't know how to do that, just reboot.

    I'm sure Belkin tells you to put the Internet in the WAN port. But they don't know you have another router there with DHCP running.
  • edited May 2007
    Okay, the laptop was already connected to a Lan Port on the Belkin Router.

    I have one connection on the back that says: Modem (I'm thinking that is the "Wan" Port, correct me if I'm wrong). The other four say: Wired Computers (Lan ports, I'm assuming). At any rate, no matter which slot its in, it still doesnt recognize my two desktops.
  • mtroxmtrox Minnesota
    edited May 2007
    Yes, "Modem" would be the same as "WAN". But lets back up.

    Here's what I know. As soon as I saw your IP addresses I knew one computer is getting its IP addresses from a different device than the other two. I guessed a VoIP router as those often have a DHCP server in them. But now I find you have two routers: the Netgear wired and the Belkin wireless. You have essentially put a hardware firewall between the laptop and the rest of the network.

    We could make it work that way, but we'd be trading posts for the next 4 months.

    Is there any reason you can't ditch the Netgear and just have everything run out of the Belkin wireless router? That way you would have one router between your computers and the Internet, and nothing between your computers. Two of them would plug in, one would connect wirelessly....all from the Belkin.
  • edited May 2007
    Yeah, I could do that, but I dont like the Belkin over the Netgear. But, maybe I need to just go ahead and do that?

    Personally I'd rather have the Netgear too, but the way you're set up, one is giving out 192.168.2.xxx's and the other is giving out 192.168.0.xxx's. That's why your network isn't working.

    I have a question! stupid one... )))
    Am i able to change my ip? (maybe hide or smth like that)
  • mtroxmtrox Minnesota
    edited May 2007
    I'm not sure what a "smth" is, and there is no short answer to your question. It depends on if you mean your public IP or your private IP...and even then it would take a long time to tell you how. A better way to get at what you want is to ask, "Why do you want to change your IP?"

    mtrox, thanks for all your help and patience with this thread. i have decided to just leave the 2 desktops networked together, apart from the laptop.

    thanks alot,

    Um, I can solve your problem for you.

    My friend runs two devices, a switch and a router(I donated the switch since he burned out his netgear.) He doesn't run DHCP at all, since they'll both fight over what gets what. The switch I gave him acts as the primary host, and it is the DHCP server. He's disabled DHCP functions in his Dlink (The router) and told it to gather all data from the host switch by disabling DHCP. And, to be honest, running two routers with three devices is remedial to be polite. Why aren't all the devices on the same router?

    Well, only one (the laptop) is wireless, hence the reason for two different routers. I wanted all of them to be on the same router, but not on a wireless Belkin router. I would prefer to use the Netgear router for all 3 of my pc's. ;)
