Windows Server 2003 has some handy networking GUI tools that include the IPConfig command-line program which let you find some helpful utility, however you should understand the options you have when using this utility for performing certain operations.

Simply by just inflowing ipconfig at the command line it will return the basic addressing information for your system, which will include the adapter name, IP address, subnet mask, and default gateway.

Here is the list of the existing parameters of IPConfig that should be useful to you.

* /all: let you know all networking information for the system that comprise the host name, node type, adapter names, MAC addresses, DHCP lease information, etc.

* /displaydns: show contents of the DNS resolver cache. This cache keeps DNS information earlier resolved in a local cache for the time period specified in the original request’s (Time To Live) TTL.

* /flushdns: clear the contents of the DNS resolver cache.

* /registerdns: reinstate all DHCP leases on the machine and reregisters them with DNS services.

* /release [adapter name]: after you identify an adapter name or fractional matching name with this parameter, IPConfig releases the address for the specified adapter. If you don’t specify an adapter, IPConfig releases all IP addresses.

* /renew [adapter name]: once you identify an adapter name or partial matching name with this parameter, IPConfig revamp the address for the specified adapter. If you won’t specify an adapter, IPConfig renews all IP addresses.

* /setclassid [connection name][DHCP server class]: This parameter induces the client machine to obtain its DHCP information from a diverse class. The class specified must exist at the DHCP server.

* /showclassid [connection name]: In case the DHCP server has provided a DHCP class, this command will show the details of that class. A DHCP class defines different parameters for different classes of machine.
