NETWORKING:
ipconfig: Here are the two most useful commands for ipconfig and usage:
ipconfig /release – This will release any IP information that the computer was given and make your IP address 0.0.0.0
ipconfig /renew – This will ask any DHCP servers (usually your modem/router) for a new IP address.
ping – Check a connection or computer
Ping is used to check the health of a connection. The ping command will tell you whether a network device is responding and how fast it is running. The ping tool can also be used to convert a web address into an IP (eg. www.google.com = 74.125.19.99). Usage:
ping www.google.com – Pings a webserver to see if it can be reached or is responding. I personally use this to see if the computer I am on can reach the internet.
ping 192.168.0.1 – Pings a local address, often a modem, router or another computer.
netstat – Displays current TCP/IP connections
netstat – Will display what connections are currently active on the system. Useful for spotting programs calling back to base such as spyware.
SYSTEM:
systeminfo – Displays information about the system
systeinfo – Will display information about the system such as the name, version, uptime, specifications and patches installed.
tasklist / taskkill – Shows what programs are running on the computer and can kill them
tasklist – Will display all the processes running and their memory usage.
taskkill – Will kill a process. Usage would be: taskkill firefox.exe
sfc – Launches Windows’ system file checker utility
sfc /scannow – This command will start scanning your computer for any damaged or missing windows system files. Useful to run after a virus, adware or spyware attack has damaged core files. Have an XP CD handy for this one.
chkdsk – Can check a disk and attempt to recover data in bad sectors.
chkdsk /f /r – This will check a disk for errors and try and fixes information from bad sectors
chkdsk /x – Forces the volume to dismount first.
For further information/usage on any of these commands, you can bring up the help for each one of them by typing:
command /?
