DNS Problems and Resolutions

Ever have a situation where you cannot access a machine by name? Perhaps your DNS (Domain Name Service) has cached an incorrect value locally. A colleague showed me how to clear entries so they can later be regenerated.


Windows:

• Start - Run - cmd
• type ipconfig /flushdns

MAC:

• sudo dscacheutil -flushcache

Linux:

• sudo /etc/init.d/ncsd restart
