Recently, our company found that some users were disconnected from the Internet. According to Microsoft's relevant security bulletin, this is because the Windows operating system of the user's PC is not patched and there are loopholes in the system. When attacked by network worms, there will be failures such as network disconnection and inability to access web pages. To this end, our company provides the following solutions, please check and patch them in time to avoid affecting the Internet.
In August 2006, Microsoft issued several security bulletins and fixed several emergency security vulnerabilities. Among them, MS06-040 security bulletin fixes a remote overflow vulnerability in server services, which allows attackers to remotely invade and completely control the operating system. At present, worms that exploit this vulnerability have begun to spread widely. The worm may install a backdoor on the infected host, and the infected computer may have the following phenomena:
(1) Network access is abnormal. For example, after dialing in, you can't open the web page.
(2) Frequent disconnection, unable to dial again after disconnection, and returning to normal after restarting the computer. The same failure occurred shortly after dialing again.
We strongly recommend that users who use Windows operating system immediately check whether your system is affected by this vulnerability and solve it according to the solutions we provide.
1. Users who have not installed the patch should install the relevant patch as soon as possible. Major virus manufacturers have increased the killing of this worm. Users who have been infected should upgrade to the latest virus database for killing.
Download the MS06-040 patch from the following website:
Chinese version: windows 2000-kb921883-x86-CHS. Exe (for Windows 2000 operating system)
windows XP-KB 92 1883-x86-CHS。 Exe (for Windows XP operating system)
Windows Server 2003-kb921883-x86-CHS.exe (for Windows server 2003 operating system)

Users can upgrade and load the latest service pack through Microsoft Windows Update.
2. It is recommended to enable the built-in firewall of Windows XP and Windows Server 2003. If you are running Windows 2000, you need to use a third-party firewall product to block TCP ports 139 and 445.
The majority of computer users should upgrade and install system patches in time, uninstall unnecessary services, and close unnecessary ports to improve the security and reliability of the system.
