Disable the CMF 6.1 IPv6 network discovery

Hello

I noticed that I was starting to get "no record found host" when you try to "View host Profile" for internal IPv4 addresses. We're a boutique IPv4 is said by the way. When I looked at the map of the network, I see the guest table [IPv6] fills and discovered entries seems really weird.

Is it possible to tell the entire firepower, modules and all jump IPv6 completely and only use IPv4?

Concerning

Fredrik

Go to policy > network discovery. There you should find one or more different rules for the network discovery.

These rules define which network discovery of segments is activated. You will see in the default configuration: / 0 which means all IPv6 addresses. I have attached a screenshot on how to delete a rule IPv6 addresses.

Where: / 0 isn't in your discovery rule, let me know your CMF version, because you might hit the bug I mentioned earlier.

  • How to disable the registry or command line network discovery / CMD?

    Hello

    We have 8 embedded windows.

    We don't want this popup about how to connect to a new network or router:

    There is no such GUI as shown here:

    http://Windows.Microsoft.com/en-us/Windows/enable-disable-network-discovery#1TC=Windows-7

    We need to turn it off via the command line or the registry, or both.

    Support and advice appreciated.

    Thanks in advance.

    You can still get the same GUI that allows you to turn it off.  Simply go to the network and sharing Center and the "change advanced Sharing Options" will be on the left.

    Network discovery is disabled by default for public networks. Changing a network location type to home or work is the best way to turn on network discovery. To learn how to change a network location type, see Choosing a network location. To enable discovery manually, follow the steps below.

    To turn on network discovery

    1. open the network and sharing Center by clicking the Start button, clicking Control Panel, clicking Network and Internet, and then click Network and sharing Center.

    2. If network discovery is off, click the arrow button expand the section, click turn on network discovery, and then click on apply. Need administrator permission if you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    I also suggest you turn on discovery of the network link and check.

    Once network discovery is defined for the network, the system works as expected, but on each startup (or wake up) network discovery is lost and need to be authorized. This is the case at the time windows server 20008 r2 and windows 7

    am I missing a setting or if not is there a way I can script the selection preference on each start (/wake) upwards.

  • Network discovery cannot be activated, windows 7 Home premium.

    This problem is very simple to describe, but I do have a lot of time I can't find a solution. Help appreciated.

    In the network and sharing Center, advanced screen sharing, there is the option to turn on network discovery and file/printer sharing.

    When I put one or both these on 'on' and click on 'save changes', the screen closes without guest or delay. If I open the screen again two options are always on 'off '.

    I checked that the services concerned (DNS Client, Function Discovery Resource Publication, discovery SSDP and UPnP device host) are started and they are.

    Tried to reboot, windows update.
    Network troubleshooting is, as always, useless.

    I suspect that maybe some third party software plays a role here. I checked for malware and removing applications with a network component.

    This is probably related. I get an error 0 x 00000001, when I try and share a local printer.

    Manager tasks shows a two process named csrss.exe running, 936 kb, the other is 6532 KB. A matter of concern?

  • I am unable to stream music to Xbox because the network discovery is disabled.

    Hello.

    We just got a new Xbox and I want to listen to my music to it.  Before asking that my Os is Vista Home Basic 64-bit SP 2 with all the updated.

    Antivirus is Microsoft Security Essentials

    Firewall is Windows Firewall - on, but default settings open the port for the client to the transmission

    The problem seems to be that the computer browser service does not start

    It is configured to start automatically.  Regstry settings show that this is supposed to start.  (MaintainServerList Yes)

    Server, Workstation, and RPC can also be programmed to automatically start.  They do not start.

    I would try to start it in safe mode, but the server does not start in safe mode. For the computer browser does not either.

    When I try to start the discovery of the network, I click Yes and it confirms that I am an administrator.  Refreshes the window and he came off.

    The strange thing is that if I look at the map of the network, I can see the Xbox and our laptop.  But in network, it asks me to turn on network discovery and file sharing.

    I tried to start the service with

    net start "computer browser".

    It was not an error.

  • Configuring the private network or disable questions for the network discovery in network and sharing Center.

    I just got my laptop all cleaned and had everything updated. When I got it back I was mainly concerned how my network and discovery sharing would work, because we never had a home computer and a laptop computer at a time. Our PC at home has always defined for a private network. Today, they are both defined for the private sector, the laptop will probably always be at home too, but I was curious to see how the printer share everything would work on my laptop. It would not print and I checked just the settings that the guy I of any program for me usually had the top settings. On my laptop that I was first checking out and the network discovery has been to custom on both, one on my PC was on, laptop has never been verified we or off, file sharing has been enabled on both. public folder sharing off on both, printer sharing turned off the PC at home, but on laptop, so much time, I guess me to turn on the PC I don't know yet. Printer password sharing is on the PC and laptop. I try essentially whether it is what you would call a custom setting make for a firewall setting, or could someone please just kinda tell me if the sharing of network discovery should be turned on on the laptop and the PC, or was it not suppose to be turned on to the laptop, but on the PC only? Which should be lit and which should not be enabled in the configuration of the private network? I just want to be able to print my laptop if I want to. Thank you

  • Network discovery, file sharing settings keep changing by itself and Alltel to set the network location continues to ask the wireless device

    former title: network location settings. Discovery of NW. File sharing. public folder sharing. AVG 9.0 'tools' and network connections.

    My Alltel Wireless device again set the network location. And continues to change my network settings for the discovery of NW to:, as well as file sharing for: file public and sharing: read-only.  I have AVG Security 9.0 and under 'tools' and connections network shows several svchost with States reading service connections listening and unknown. I don't want no access to my computer and cannot find any computer consultants who can get this to stop. What can I do?

    Hello
     
    1. the options apply automatically on?
    2. have you made changes on the computer recently?
    3. have you installed any Alltel Wireless application to manage network connections?
    4. What is the current network location type on? Is it home, work or public?
    Network discovery and file sharing settings depend on the network location. For examle, if you set the network as a public location it turn on file sharing.  So I would ask you to turn all the parameters and then choose the type of network and check if the parameters change again.

    Method 1.
    I recommend you to check if the problem exists in clean boot. May be a third party application is causing these changes.
    See the article below for instructions on how to start your computer in a clean boot state.

    Note: When the diagnosis is complete, don't forget to reset your computer to normal startup. Follow step 7 in the above article.
     
    Method 2.
    Also check the settings under tools in AVG security suite. You may need to check with the help of AVG on it.
    Or you can disable the antivirus software and check if that causes this behavior.
    Temporarily disable the security software installed on the computer and check if the problem persists.
    Disable the anti-virus software

    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.
