About windows Firewall/internet connection sharing ICS can't start
Recently, a situation appeared on my computer (XP SP2), and a SVCHOST.EXE application popped up on the Internet. Error message, similar to the memory error prompt, the network can not be opened immediately after the point is determined, the dialer can not be opened, and the ICS is set from the dialer properties, the control layout, and the system firewall is displayed: windows Firewall/internet connection sharing ICS cannot be started. You must restart your computer, but after a while, this will happen again.
If you do not restart but log off and start again, the sound icon in the taskbar disappears, and any audio and video files can't be played. There is a system sound except when it starts, and there is no sound anymore.
In the face of this situation, I went to Baidu for a multi-party search, summed up the following reasons:
1, the virus into the safe mode antivirus
2, the system has a mistake using the system restore
3, Registry error needs to be manually fixed
But I think the most useful is this Article 4, to Microsoft upgrade system, huh, huh ~
You may not know that Microsoft has another loophole, this situation is caused by this vulnerability After the upgrade, the problem disappeared. Some people said that they don't know which program to upgrade.
Open Control Panel Point Security Center Select Automatic Update Settings at the bottom Select Notify me when there are downloads available, but do not download and install them automatically. After a few minutes, the system prompts you to download and install the patch. After the installation, the problem disappears. . . . . . . . . . . . .
Or upgrade from here can also be: http://update.microsoft.com/windowsupdate/v6/default.aspx?ln=zh-cn
Computer software and hardware application website long note: from the problem, the essence is System vulnerabilities, such as non-genuine can go to down.45it.com to download 360 security guards, use the software's vulnerability patching function, will check out all the system vulnerability patches to solve the problem! !
