In addition, any manual entries in the LAN properties may be ignored if DHCP information is obtained via Group Policy DHCP configuration can be assigned via Active Directory Group Policy as well, so you may have to contact the Active Directory team for IP configuration changes.Changes should not be made to the IP configuration unless authorized or approved by the network team (they may choose to make the changes themselves) In addition, most companies have individuals or teams that handle network configuration. This is so you can maintain communication with the server in the event the configuration information is mistyped or otherwise incorrect. IP configuration changes should be made at the host console, not remotely.Multiple DNS suffixes can be used in instances where a company has multiple domains. Here you can specify additional/different DNS servers, add additional DNS suffixes that can be appended to the host name, and a static DNS suffix for that connection. NSLOOKUP is a command-line utility that allows, among other things, lookup of a fully qualified domain name based on either the host name or IP Address.

On occasions IP addresses are changed on the host, but the DNS entry is not updated either because of latency or because the host was not able to update its own DNS record (certain types of DNS providers do not allow a record to be automatically updated).Īnother method for checking name resolution, at least from the domain perspective, is NSLOOKUP. This will test how easily the name can be resolved from your workstation. The first and easiest way to check name resolution is to PING the host using only the hostname if you're local to the host (instead of the Fully Qualified Domain Name). Since the DBA group is one of the first groups to be contacted when an application fails, name resolution can be quickly eliminated as a possible cause of application failure. Tools A DBA Can Use To Troubleshoot Name Resolution This is the least efficient methods that requires the equivalent of a broadcast.

This lead to the development and implementation of other technologies such as Windows Internet Naming Service and DNS. As enterprises grew and more machines used, the task of manually updating the file on each host became unruly. In the early days of networking, and to a lesser extent now, the file (located in %SystemRoot%\System32\Drivers\Etc folder) was used as the primary method for name resolution. A Hosts file, located on each host, is queried.The latter is considered a loopback network address used to troubleshoot the network interface card (NIC). In addition to the host name given to the host, two other identifications are associated with the host - the name LocalHost and the IP address 127.0.0.1. The host first determines whether the name in question is its own name.Name Resolution and The HostThere is a sequence in which name resolution is attempted: This is one of the methods used to resolve names on hosts that host numerous websites. A host can have a number of Fully Qualified Domain Names in DNS. The Fully Qualified Domain Name of that SQL Server would be. Let's say we have a SQL Server or server farm at MSSQLTIPS with a host name Support. The Fully Qualified Domain Name is created by attaching a DNS suffix to the host name.

When looking at host names, there are at least two names associated with a host: the host name and the Fully Qualified Domain Name, or FQDN. With the impending implementation of IP Version 6, IP addresses will be even harder to remember. If it weren't for DNS, we would have to remember the IP address of every website we visit. The most familiar form of naming is called the Domain Name (Naming) System, or DNS. Name resolution is the association between an Internet Protocol (IP) address and a user-friendly computer name. In any case, name resolution plays a vital role in the application serving the client. Also, many companies use a DNS alias for a connection string to either refer applications to a server farm or as an "abstraction layer" for disaster preparedness. Most application programmers use host names in connection strings, since the IP address can be modified easier in the DNS record than it can on the host itself.

So what exactly should a DBA know about name resolution? In a nutshell, a DBA and others responsible for applications should know how to troubleshoot it.
