Earlier I was testing an issue with scanning to a Brother printer at the computer shop and needed to flush the DNS cache on my Windows 7 laptop after I made an entry on the local DNS server. Flushing the DNS cache on Windows 7 is easy using the command line from a Windows Command Prompt. Follow the directions below to clear the Windows 7 DNS cache.
