A week ago everything was working fine. Then I started having problems with Intenet Explorer. I get 'Cannot find server or DNS Error'message.

I've been told that it could be a firewall preventing me having access. I tried to uninstall Norton Internet Security and received a message 'Symantec has encountered a problem and needs to close'and I'm unable to remove Norton Internet Security. I'm trying to install different viruses programs and I'm not having any success. Could anyone please help. Many thanks, Serge. Domain Name System (DNS), a locator service in Windows, is an industry-standard protocol that locates computers on an IP-based network.

The message that I get says that the server DNS address could not be found -- DNS_PROBE_FINISHED_BAD_CONFIG. The only thing that has changed on my computer in the last week is the new version of Android plus possibly updates to Windows 10.

IP networks, such as the Internet and Windows networks, rely on number-based addresses to process data. Users however, can more easily remember name addresses, so it is necessary to translate user-friendly names (www.microsoft.com) into addresses that the network can recognize (207.46.131.137). Before DNS, a Hosts file was used -- a manually created file residing on a host computer that associates host names with IP addresses -- still used today in fact. Note: For instance, Host name addresses such as www.yahoo.com are addresses you see and may use every day and are what we recognize as intellectual information. IP addresses are numbers such as 204.71.200.67 that mean the same thing and which the computers uses to actually find the sites. Speech recognition mac. Even though a user may use either the 'Host' or 'IP address' as a site address using Internet Explorer, the computer must first look up and translate the 'Host name' to an 'IP address' before a connection is made. DNS Servers map IP addresses to computer names and computer names to IP addresses.

By doing so, they provide the mechanism to locate network resources. The DNS WMI Provider allows applications to interact with DNS Servers through the unified management framework of Windows Management Instrumentation (WMI).

A DNS Server is a computer that completes the process of name resolution in DNS and contains zone files that enable them to resolve names to IP addresses and IP addresses to names. When queried, a DNS Server will respond in one of three ways:? The server returns the requested name-resolution or IP-resolution data.? The server returns a pointer to another DNS Server that can service the request.? The server indicates that it does not have the requested data. A DNS zone is a set of files or records (more precisely, a database of resource record entries) that corresponds to part of the DNS hierarchical name space.

DNS zones are used to delineate which DNS Servers are responsible (authoritative) for resolving name-resolution queries for a given section of the DNS hierarchy. DNS zones differ from the domain structure in the following fashion: zones can be composed of one or more DNS domains. One zone in the gadgets.widgets.microsoft.com domain tree might be authoritative for the gadgets and widgets domains. DNS WMI Provider Overview a. A provider is an architectural element of Windows Management Instrumentation (WMI).
