often caused by having the wrong DNS server configured on the client, sending DNS requests that the server does not have in its database, or packet loss on the network. DNS is a UDP-based protocol, so packets that are lost will not be retransmitted, causing DNS to fail Resolution: Check the client configuration to see which DNS server it is setup to use. If this is the wrong server, adjust this setting in the client or in the DHCP server which provided it. Test the DNS server from the client connection

Unit 4. Site-to-Site Connectivity Scenario First, open the console and Services Site Links and see how long this set up for replication. Then create an object in AD and expect to replicate. Compare this with the time set in "Site and Services", and is equal to or less this ok (ok with the settings that were set) If you are the highest: Run the command repadmin / showreps and put the result here. Open the Event Viewer logs and see what errors appear. When you create a site object

of the host can potentially change often. To determine this information you can use the ipconfig (Windows) or ifconfig (Linux) utility. Some common networking issues are centered around issues with Dynamic Name System (DNS) resolution issues. DNS is used by the internet to resolve domain names to commonly unknown IP addresses. If the system does not

Abstract The expansion of the organization has allowed the IT department to design a network that will allow each office to share the same Internet Domain Name while still being located in separate offices. The organization currently own 25 servers and they expect to have to purchase up to thirty more to accommodate the new branch office. The design will allow for providing service to 5000 users with the thought of future growth being applied to the new network design. It has been suggested that

use Google Public DNS When you use Google Public DNS, you are changing your DNS "switchboard" operator from your ISP to Google Public DNS. In most cases, the IP addresses used by your ISP's domain name servers are automatically set by your ISP via the Dynamic Host Configuration Protocol (DHCP). To use Google Public DNS, you need to explicitly change the DNS settings in your operating system or device to use the Google Public DNS IP addresses. The procedure for changing your DNS settings varies according

Services 1.) The Domain Name System consists of a hierarchical set of DNS servers. Each domain or subdomain has one or more authoritative DNS servers that publish information about that domain and the nameservers of any domains "beneath" it. The hierarchy of authoritative DNS servers matches the hierarchy of domains. At the top of the hierarchy stand the root nameservers: the servers to query when looking up (resolving) a top-level domain name (TLD) Features • Scalability—Because DNS is capable of distributing
