Handle Names and Addresses Efficiently

The only way to find something on a network is to know its address. But alas, human beings are much better at remembering symbolic names than numeric addresses (or worse still, the arcane bit patterns that computers use to address one another).

This means many things when you operate a working network, but two primary concerns from a troubleshooting perspective exist:

  • The services that provide name -to-address translation must be properly configured and working correctly for users to use a network effectively.

  • Network addresses, subnet masks, and related information (such as default gateways, router addresses, and so on) must be unique, properly specified, and in substantial agreement for computers to use a network properly.

Symptoms of trouble in this area are many and varied. Duplicate addresses usually cause all holders of the same address to lose their capability to access the network. Invalid names or addresses simply can't be reached and may require serious troubleshooting to correct. Active Directory may be unavailable or not working for some reason or another. (In general, check the spelling of names carefully and the numeric values for addresses equally carefully .)

Fortunately, problems in this arena usually make themselves known during initial configuration or when settings change. If you can simply check your settings and assumptions against a known, working set of values, you can usually correct these troubles quickly and painlessly.
