Even though the networking GUI tools in
Windows Server 2003 have been refined, the IPConfig command-line
program is still your best bet for performing certain operations.
So it's important to understand the options you have when using
Simply issuing ipconfig at the command line
will return basic addressing information for your system, including
the adapter name, IP address, subnet mask, and default gateway.
Here's a list of the parameters that are
available in IPConfig:
/all: Shows all networking
information for the system, including host name, node type, adapter
names, MAC addresses, DHCP lease information, etc.
/displaydns: Shows the
contents of the DNS resolver cache. This cache keeps DNS
information previously resolved in a local cache for the time
period specified in the original request's TTL (Time To Live).
/flushdns: Clears the
contents of the DNS resolver cache.
/registerdns: Refreshes all
DHCP leases on the machine and reregisters them with DNS
/release [adapter name]:
When you identify an adapter name or partial matching name with
this parameter, IPConfig releases the address for the specified
adapter. If you don't specify an adapter, IPConfig releases all IP
[adapter name]: When you identify an adapter name or partial
matching name with this parameter, IPConfig renews the address for
the specified adapter. If you don't specify an adapter, IPConfig
renews all IP addresses.
name][DHCP server class]: Forces the client machine to obtain
its DHCP information from a different class. The class specified
must exist at the DHCP server.
name]: If the DHCP server has provided a DHCP class, this
command shows the details of that class. A DHCP class defines
different parameters for different classes of machines.
