  1. I have an odd situation I'm hoping someone could help me out with. I have a user who is getting the yellow exclamation point complaining about no internet access. We have a domain (win 2k3) and he still has access to all the local network resources, but can't get outside the building. This issue is isolated to just his computer, as everyone else has no problem (I'm typing this message from another PC w/ exactly the same specs on the same network).

    System Specs

    ZOTAC 880GITX-A-E AMD3 motherboard

    8GB RAM

    Win7 Pro x64

    Realtek PCIe GBE controller

    Atheros AR9285 wireless

    We use the wired LAN as the default connection for all the desktops (wireless is active but not connected). I switched him over to the wireless (unplugging the wired connection), and the problem did go away, his internet access was restored. After about 10 minutes the problem came back and now affects his wireless connection as well.

    I'm stumped. I've followed most of the steps I've seen online (disabled and enabled the devices, disabled IPv6, /flushdns, disconnect from power, etc...), and all to no avail.

    Any suggestions?

  2. So I finally gave up and wiped the drive. Unfortunately because he doesn't have his original disks I couldn't use them to re-install windows, so I had to download a copy of XP SP3. Got windows installed, but Activation doesn't want to take the product key that's on the bottom of his PC. I tried calling MS, and after they reject the installation ID, they tell me to go to support.microsoft.com/pag, which tells me that XP is no longer sold and I have to buy win7. Is there any way around this? He has a legal copy of windows, so I'd rather not crack the activation.Any suggestions?

  3. Therefore, i would suggest to check registry for such entries.

    Any suggestions as to where I should look? I've already deleted the winsock and winsock2 reg entries and had Windows recreate them.

    I would format anyway as you can't know for sure if you didn't missed something else when there are many virus/trojans.

    Did you checked if the loopback was still working (ping 127.0.0.1) ?

    Also, the error message you get is usually related to .net framework so may be removing it or reinstalling it might solve the problem.

    I'm still holding out hope that I can avoid a reformat, as much of a pipe dream as that may be. I've been able to scan the system in safe mode with spybot and hijackthis and ms security essentials with no hits, so I'm reasonably confident the system is clean.

    I haven't tried the loopback yet. What will that tell me? I'll try deleting the .net framework if he has it.

    Although it doesn't sound like your issue, I've noticed that a common leftover after virus removal for users of Internet Explorer is usually fixed thus:

    navigate to

    Internet Options > Connections > LAN Settings > Proxy server

    then

    Uncheck the Use a proxy server for your LAN checkbox

    That was unchecked and I rechecked the "automatically detect settings" box as well. No change in behavior.

  4. Hi guys,

    A friend of mine brought me his laptop (XP SP3) claiming it was acting slow. Turns out he had a mess of viruses -- some trojans, google redirect... pretty nasty stuff. I finally got all that cleaned off (no small feat given the virus auto-rebooted out of safe mode), and now I can't get online. Whether I use wired or wireless, DHCP or static, nothing works. Renewing the IP fails, claiming the "socket operation encountered a dead network". Static IP's fail to get a DNS lookup

    I've tried all manners of winsock2 resets (both commandline and programs)

    I've reinstalled TCP/IP on both adapters

    I've uinstall the wireless and wired adapters and had windows reinstall them

    I'm hoping I've missed something or someone has worked through this before and can offer me some suggestions. It's a Gateway laptop, and he claims not to have the original XP Home disk, so I don't know how possible a clean wipe/reinstall is (plus he's really pressing me not to go that route)

    So, any suggestions?

  5. Unless you're going to be moving a lot of files across that network, 10/100 should be fine, but if you're going to be doing structured cabling (running it through walls and such), then don't bother with 10/100 and do as fast as you can afford.

    As far as optimal placement, so long as you're using switches and not hubs, your placement is fine (given the quantity of devices), and there would be no real benefit to putting in any more routing devices.

  6. Yeah rendrag your probably right, anyway MW2 on PC is almost a direct console port (except for in game text chat, mouse support, and changing graphical options..."oh wow").

    BTW, because MW2 on PC goes through Steam that means Steam gets some cash too so any copy sold on PC would only make as much as a console copy (give or take a bit, but it still makes less that usual).

    Right now, there are no licensing costs to sell on Steam, so Valve doesn't make a nickel when a game is sold that way. That's why games are generally less expensive for the PC than for the consoles.

  7. IW will just use low sales as an excuse to move further away from the PC platform. It's unfortunate, but I understand why they would go down that road - almost 0 piracy problems and no support issues (since the hardware is static). That means fewer bugs, which means fewer ongoing costs. Even though they pay the licensing fee to Microsoft and Sony, they still make a bigger margin on the game for the console than the PC.

  8. start by finding out the exact model number of that router and get it's documentation. generally much of the problems with access and connection issues are misconfigurations in the routers interface.

    All of what you want to do can be achieved, but before introducing more hardware into the mix (1TB external drive) make sure everything else is working rock-solid, otherwise you will only drive yourself more nuts.

  9. the pfsense box is certainly going to be more powerful and have many more configuration options compared to any consumer grade device. If you can get it working, there's no reason not to use it, especially if you feel you need or want that level of control over every aspect of traffic coming in our going out of your network.

  10. can you define "disappear"? That's not really a technical term that we can understand. Can you give us some information on your setup, what operating system, what steps you took to create and replicate the problem etc...? We'd love to help you, but the reason no one answered your initial question is because you really gave us no information.

  11. You could get a mac address by pinging it, then doing an arp -a.

    do a lookup on the vendor ID of the mac. This will give you an idea of what brand the product is, and probably narrow your search a bit more.

    that will just give the vendor of the NIC, which is not always the vendor of the product.

  12. need? no. You do not need to terminate the cables into a patch panel. You could just as easily terminate the ends of the wire into an RJ-45 jack and plug them into whatever switch you want. The beauty of a patch panel, and why I chose to terminate into one with my house project, is that it looks much cleaner.

    I have a finished basement "office" where all my gear is. I didn't want a bunch of wires coming out of a hole in the wall, so I fastened my patch panel right into the hole I cut so that it sits flush on top of the sheetrock and all the wires are hidden. I thought it looked much cleaner. Then I run individual wires down from each port on the panel to a 24-port gb switch mounted in a 13U APC rack with some other stuff. Every 6" or so of exposed cable I use a velcro tie-wrap so that it looks neat and tidy. This allows me to run multiple lines to various places in my home, but knowing that the lines aren't active yet, I don't necessarily need to run the cable from the patch-panel to my switch.

    It depends on your situation though. If you're setup is just in a utility closet and you don't care about neatness, then you don't need a panel. Just make sure you use some kind of labeling system on the cables (whether you use a patch-panel or not) because you'll quickly forget which cable run goes where.
