Install Internet Protocol Version 4 (TCP/IPv4) on Windows 7


I can not explain what has happened, just suddenly I lost my internet connection. On local area connection properties IPv4 is not installed, my ISP says that they only support IPv4. Then I must had it because I had connection before. What could happen to lose IPv4? And how to install it back?


Thank you.



Answer



way 1:


Run cmd as Administrator. Run command:


netsh interface IPV4 uninstall

Wait 2-3 minutes, run:


netsh interface IPV4 install

way 2:


Run cmd as Administrator. Run command:


resets WINSOCK entries to installation defaults


netsh winsock reset catalog

resets IPv4 TCP/IP stack to installation defaults:


netsh int ipv4 reset reset.log

or


netsh int ip reset reset.log

need reboot


way 3:


Run ncpa.cpl as Administrator.


Right-click the network connection which you are using, and then click Properties.


Click on Internet Protocol TCP/IPv4.


Click Install then.


Click Protocol, and then click Add.


Click Have Disk.


Type the location as %windir\inf%, example: C:\windows\inf and then click OK.


On the list of available protocols, click Internet Protocol (TCP/IPv4), and then click OK.


way 4:


wmic nicconfig get MACAddress, IPAddress, ServiceName, Caption, IPEnabled, SettingID | find /I "Realtek"

Get NIC GUID and del HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00x\Services\{GUID} in registry.


wmic nic get Caption, PNPDeviceID, ServiceName, NetConnectionStatus | find /I "Realtek"

Get NIC PCI ID: PCI\VEN_XXXX&DEV_YYYY&SUBSYS_ZZZZZZZ&REV_TT and del HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00x\Enum\PCI\VEN_{PCI_ID} in registry.


If it is difficult steps to improve law, registry entries, and then override the owner can use the Windows Driver Kit (WDK) 7.1.0.


Run regedit with SYSTEM rights.Need Windows Driver Kit (WDK) 7.1.0:


ntsd -c qd regedit

Scott Chamberlain (c), good comment!:


You can run regedit with SYSTEM rights by using PSExec too, much smaller download. One of the examples they post is running regedit as SYSTEM.


psexec -i -d -s c:\windows\regedit.exe

Reboot!


way 5 (apply if in a pinch, if the previous methods did not help):


/1. Back up Registry /2. Edit file %windir%\inf\Nettcpip.inf in [MS_TCPIP.PrimaryInstall]


comment string ;:


;    Characteristics = 0xA0 ; NCF_HAS_UI | NCF_NOT_USER_REMOVABLE

and add


Characteristics = 0x80

Nettcpip.inf ipv4 enable Uninstall


/3. Control Panel->Network Connections->Local Area Connection->Properties


enter image description here


Install protocol. Press Install button, select protocol, type Windows Inf path.


enter image description here


Select IPv4 protocol. (Unblock IPv4 uninstall button.)


enter image description here


Uninstall IPv4.


enter image description here


/4. delete registry key:


HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2

if need, delete registry key:


HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\tcpip
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\dhcp
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\dnscache
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ipsec
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\policyagent
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\atmarpc
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\nla

enter image description here



enter image description here


/6. Install IPv4

keyboard - Is there any utility/method to change Windows key bindings to type rare chars to currently empty bindings?

I'm currently typing this post with my windows XP machine and (Spanish) keyboard, and I'd like to add some extra symbols to my text. I could open the "char map" windows utility, look for the desired symbols, and paste them. But I'd like something quickier. For example, when I'm using my OSX Mac at work, I can easily add a ©, ™, ® or similar symbols, just pressing some weird ALT-GR + G / H / J, key combinations. In my (Spanish) keyboard mapping, these combinations are empty, as they don't produce any char at all, which, on the other hand, is perfectly normal and desirable. So, I thought: Why couldn't I add some extra key mappings on top of my currently empty ALT-GR + G/J/H Keys in my Spanish keyboard, and thus, being able to quickly type these special symbols? So that's my question: Is there any utility/method to achieve that effect under windows? (My version is XP). I've even googled this for some time but no luck. I've been a long term Hot...

virtualization - How to select paravirtualization interface in VirtualBox?

Given a windows 8 host system (Intel Core i5) and a Linux Fedora host, I would like to determine the optimal setting for the paravirtual interface. Options are none Default Legacy minimal Hyper-V KVM This page suggest the selection is only based on the guest system: The biggest change in VirtualBox 5.0 is the introduction of paravirtualization support, bringing higher performance and time-keeping accuracy to supported guest operating systems (Hyper-V on Windows and KVM on Linux). Is that correct? Answer The VirtualBox Manual , in the section titled Paravirtualization providers explains very clearly when each should be used (emphasis added): Minimal: Announces the presence of a virtualized environment. Additionally, reports the TSC and APIC frequency to the guest operating system. This provider is mandatory for running any Mac OS X guests. KVM: Presents a Linux KVM hypervisor interface which is recognized by Linux kernels starting with version 2.6.25. VirtualBox's implementati...

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...

security - How is Linux not prone to viruses, malware and those kinds of things?

How is Linux protected against viruses? This question was a Super User Question of the Week . Read the blog entry for more details or contribute to the blog yourself Answer Well, it factually is not... it's just less subject to hackers developing viruses that target Linux systems. Consumer grade computers usually run on Windows and thus, when targeting a wide audience, Windows is the way to go. Don't misunderstand Linux and viruses, there definitely ARE Linux viruses. Some distros have additional protection layers such as SELinux (See here ) in Ubuntu for example. Then there's the default firewall and the fact that alien files don't automatically have permission to be executed. Specific execution permission has to be granted before execution is possible. (See here ) Then there are several other factors that make Linux a hard place to be for viruses usually non-root users on linux systems have no to little executable files at their disposal that would allow for virus...
