Windows cannot discover any computer or device

Hello

I am to evaluate Windows Server 2012.

I've set up a small network size, with a server (Windows server 2012), a switch and a workstation (Windows 7). I set up a domain.

In my computer (Windows 7), when I try in "Network and sharing Center" feature run the "see the whole map" I get: "Windows cannot discover any computer or device.

Reboot in 'safe mode with network', and repeting the operation fails the same, but with a different message: "Windows cannot start mapping on the adapter. Please make sure that the adapter is connected and active.

I checked the card through "Control Panel\All Control Panel Items\Troubleshooting\Network and Internet". Result: "Troubleshooting couldn't identify the problem.

The State of the map is:

IPv4 connectivity: Internet
IPv6 connectivity: No network access
Media state: enabled

The adapter is a "Atheros AR8151 PCI - E Gigabit Ethernet Controller (NDIS 6.20)", and the motherboard is recent (a Gigabyte GA-Z77X-D3H).

In addition, I ping the Windows Server 2012 of the Windows 7 workstation and vice versa. Remote Desktop connection works too well.

"Network control and Internet\Network and sharing sharing settings Center\Advanced" the Windows 7 workstation, I duly turned on "network discovery.

Also, I have disabled the windows firewall for both machines, without result.

What can I try something else? What could be?

Thank you

  • "Windows cannot repair this computer automatically" - Satellite C660-108

    Got a new laptop for Christmas yesterday and it worked fine yesterday, I came home tonight and he asked me to click on restore and then restart. I realized that, now, whenever I go to turn on the machine, it brings the message "Windows cannot repair this computer automatically" and a saying to have connected external devices to and remove, then (which I don't have)...

    Was called "The Tech Guys" they said it was probably because when I started the laptop arrived so many updates etc and one of them went bad and I need to call back with the front desk and they'll go through it with me.
    So I intend to do, but I would like it if people could give advice on how to solve this problem.
    Thanks :)

    In my view, ting best that you can do now is to reinstall the OS using the recovery disk.
    After the own pre-installed operating system it will be working correctly again.

    How to do this you can read in the document or as a result of this document - s user manual http://aps2.toshiba-tro.de/kb0/HTD9102IR0000R01.htm

  • WINDOWS CANNOT FIND ANY ADDITIONAL NETWORK (DIAL-UP AND VPN) OTHER THAN THE WIRELESS NETWORK

    ehmm I just installed nokia 6600 pc suite on my computer so I can access the internet on my computer through the usb cable. Installation and drivers have been installed correctly. I can access the internet on the handset but when trying to connect to the internet via USB with the computer "I get a message that windows cannot find any additional network." Its really disturbing that I can do to fix this. Can someone help me please.

    Even if a USB device, it does not create a new network connection for you.  I fear also that you use a regular USB cable - those connections often require a crossover cable (but more on that later and I guess it should work it is how it is advertised).  Go to start / Control Panel / Network and sharing center / set up a connection or network / and choose the first option (you can also check the main page to see if the connection is listed but I doubt it).  Choose to set up a new connection and follow the instructions - ensuring that you enter the correct settings when it is required.  You should perhaps install device drivers, firmware and or software for the device to work properly - read the installation mode (and call technical assistance from Nokia to help you put in place - they know more about what we do and should be happy to guide you through the process and even to set the settings on your computer until you log - that's what I would do in your before circumstane even of) ask for help here).

    To start / Control Panel / Device Manager and check all the new drivers (double clck on them) to confirm that they say that they do not work properly.  Go to start / Control Panel / Add Haedware and have the system check new hardware devices - if it finds, install them (it is perhaps what is missing in this process).

    I hope this helps.  If nothiing suggested I bring, don't hesitate not to contact Nokia for assistance - I'm sure they'll have you place and operate at any time.  Keep me in the loop.

    Good luck!

  • Windows cannot find any networks, but Ubuntu can! (X 32 Vista Home Premium)

    I recently replaced a faulty laptop computer mother board with an identical model (only difference is a newer version of the BIOS). After restarting Windows (Vista Home Premium 32 bit) I can't find the networks wireless where I can see usually eight networks at least an unsecured connection, but now I get nothing.

    I replaced the wireless card Atheros with an Intel Pro 3945ABG driver and installed the latest version and that I still get the same error "Windows cannot find any networks", I can get access to the internet via an Ethernet cable but I am unable to connect wirelessly. If I try to manually configure the wireless connection, I get "unexpected error occurred".

    I started the system from a CD of Ubuntu to check that it was not a hardware problem. Wireless card perfectly, sees all the networks, connects and works very well.

    It seems that something inside Vista has failed since even change the wireless adapter for a different manufacturer and the results of the modeling in the same error, pointers?

    Kind regards

    Jason.

    SOLVED

    It turns out that Kaspersky Internet Security is at fault and he was very happy to work via ethernet it had mutilated all WLAN connections.

    Removal of Kaspersky and all of a sudden all the wireless networks have re-emerged.

    Kind regards

  • Windows cannot repair this computer automatically (Vista) after changing the motherboard

    Thank you

    Clarification:
    Windows Vista is preinstalled on this system?
     
    If I read (and cited only) correctly - Yes, which is not going to work.  The license for Windows Vista was related to the Compaq system motherboard.  If you had that repaired under warranty, HP? Compaq could have helped you.  As you have created a new machine (motherboard especially) now, you will need to purchase a new license for Windows Vista or any other operating system of your choice.
     
    You could, I suppose, buy the OEM of Windows 8 version.  You will have the same problem later (OEM licenses is related to the first motherboard it is installed and activated with.)

  • Windows cannot find any additional network / an unexpected error has occurred

    I got this new PC Windows Vista Home Edition x 64 SP2 and I need to connect it to the network wireless in my house because that the router Netgear DG834GT wireless broadband is not very conveniently placed for wired connectivity. I have a Netgear WG111T USB wireless adapter which works fine on my other PC / laptop (XP & Vista, both 32-bit), but I can't make it work on my Vista x 64 PC.

    I have installed the version of the driver 2.1.0.26 x 64-compatible for the WG111T and the device works correctly, according to Device Manager.

    When I try to 'connect', I get 'Windows cannot find any additional network . " While the other PC at home can pick up 3 wireless networks.

    Go until the network & sharing Center, then manage the networks without wire, then Add, then manually create a network profile, I get "unexpected error ."

    I spoke to Netgear who insist the player WG111T is compatible with the x 64 visits.

    I talked to my PC provider who suggested to try the adapter on another PC Vista x 64 to see if it works there. Problem is, I don't know anyone else with a Vista x 64 PC.

    I would be extremely grateful if someone can help me before on this one. Thanks in advance for all advice.

    See you soon,.

    It seems that the problem was caused by ZoneAlarm Internet Security Suite hinder and prevent the correct installation of the Netgear wireless driver.

  • Windows cannot find any neworks with Wi - Fi

    I have a Toshiba laptop that connects to the internet via a Belkin N router.

    During an internet session, the laptop can lose connection and if I try to connect to a network I get the error message "Windows cannot find any network."

    Nothing has been changed during the session.

    Laptop computer shutdown and restart will allow the laptop to auto automatically reconnect to the preferred network.

    My impression is that it is a software problem.

    Hi kaspercat,

    Rather than restart you tried the option "diagnose and repair"? Right click on the internet icon (two monitors flashing) in the notification area and in the menu drop-down, select diagnose and repair. This usually works fine for me if the laptop on my network loses connection.

  • Windows cannot reset your computer

    My computer says windows cannot reset your computer... Please help me to reset my computer...

    The original product key is embedded in the motherboard of the laptop UEFI firmware, so you're not going to lose...

    If you restore using recovery media HP, which will retrieve the key automatically and reactivate the original OS.

    However, you have already saved your PC running Win10 with Microsoft. So, if you decide to install Win10 instead, as long as you install the same version you already running, once the PC connects to the Internet, it will communicate with the Activation of MS servers and automatically reactivates.

    Good luck

    Hello

    Maybe this can help.

    These steps and tell us where is the breaking point.

    Check the Device Manager for the wireless card valid entry.

    http://www.ezlan.NET/Win7/net_dm.jpg

    If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

    Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

    http://www.ezlan.NET/Win7/net_connection_tcp.jpg

    ------------------

    The wireless card drivers much also install utility wireless of the seller.

    Make sure that if there are teas from Wireless Utility of seller does not work with the native Windows wireless utility (Service WLAN).

    ----------------

    Make sure you firewall No. preventing / blocks wireless components to join the network.

    Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

    If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

    party like Hello and NetMagic 3rd network managers can block local traffic too.

    ---------------------------

    Stack TCP/IP work should look like.

    Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

    http://www.ezlan.NET/Win7/status-NIC.jpg

    Description is the data of the card making.

    The physical address is MAC of the card number.

    The xx must be a number between 0 and 255 (all xx even number).

    YY should be between 0 and 255

    ZZ should be between 0 and 255 (zz all the same number.)

    The date of the lease must be valid at the present time.

    * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

    * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

    ---------------------------------------------------

    A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

    Above everything is OK, you must be able to connect to the router.

    Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

    If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

    Important note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

    Note: You should not turn off Windows Firewall unless you have another firewall is enabled. Turning off Windows Firewall may make your computer (and your network, if you have one) more vulnerable to damage caused by worms or hackers.
