Other Command Lines
To find out a remote
computer's MAC/Physical Address, use arp -a ip, for example, arp -a
192.168.0.1. Another way to find out MAC is check DHCP records. To find local
computer MAC, use ipconfig or winipcfg.
When troubleshooting a TCP/IP networking problem, you can use the
ipconfig command to get host computer configuration information, including
the IP address, subnet mask, and default gateway. If it is running Win9x, ME,
use winipcfg instead.
When troubleshooting a TCP/IP networking problem, you can use
the ipconfig /renew command to renew all network adapters on the
computer that uses DHCP (except those that are manually configured) try to
contact a DHCP server and renew their existing configuration or obtain a new
configuration. You can also use the ipconfig command with the
/release option to immediately release the current DHCP configuration for
a host. For Win9x and ME, use the release and renew options of
the winipcfg command instead of ipconfig /release and
ipconfig /renew to perform manual release or renewal of the IP
configuration lease for a client.
Flush and re-register WINS and DNS
To
flush the NetBIOS cache, use nbtstat -R, and to
re-registers with WINS, use nbtstat -RR.
To flushes the DNS cache, use
ipconfig /flushdns, and re-registers with DNS, use ipconfig /registerdns.
