Host file suffix changed to. ics

Question:

C: \ Windows \ System32 \ drivers \ etc has a host. ics file, and the original host (without the extension) also exists. The file is normal. Sometimes the web page cannot be opened. You can access the Internet after you delete host. ics, but it will be created after you restart it.

Answer:

Host. ics File: the host provides a connection to the existing TCP/IP network through the second network adapter. Log on as a member of the Administrators group to set the ICS host. That is to say, the default network is not WIN! Do not use ICS: 1 on the following networks. 2. A network with a Windows Server 2003 domain controller. 3. Use networks of other DNS servers, gateways, or DHCP servers because ICS creates static IP addresses for your network adapters and assigns IP addresses to other computers on the network, therefore, if other network computers already provide these services, you will lose connection to other parts of the network. If one or more of these conditions exist in your network, you must use Windows Server 2003 NAT instead of ICS. Do not create a virtual private network (VPN) connection from the ICS computer to the company network. By default, all traffic from ICS computers (including the traffic from LAN clients) will be forwarded to the company network through a VPN connection. This means that Internet resources will no longer be accessible, and all clients will send data through a logical connection created using the creden of ICS computer users. Do not configure ICS on the computer that acts as the VPN Server. If a computer based on Windows Server 2003 acts as a VPN Server, you must use Windows Server 2003 NAT. Your problem is simple: delete files. If you install a PPPOE protocol at home (ADSL) and use it to access the Internet, if the company sets the IP address of the Network Gateway to 192.168.1.1, it will be OK.
