Q: Mac Mini, Mac OS X 10.5.8, DNS Flushing

A company recently changed its IP Addresses, and since the browser reported "Cannot connect to the server", have tried to flush the DNS using the Terminal Commands

i) dscacheutil -flushcache

and

ii) sudo dscacheutil - flushcache

 

Given that the browser returns the same error message, can anyone recommend troubleshooting steps.

 

Thanks

    Hi, this has worked for a few...

     

    Though all of these steps may or may not be needed, I'm including them all.

     

    Make a New Location, Using network locations in Mac OS X ...

     

    http://support.apple.com/kb/HT2712

     

    10.7 & 10.8…

     

    System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

     

     

    10.5.x/10.6.x/10.7.x instructions...

     

    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

     

    The interface that connects to the Internet should be dragged to the top of the list.

     

    10.4 instructions...

     

    Is that Interface dragged to the top of Network>Show:>Network Port Configurations.

    If using Wifi/Airport...

     

    Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

     

    For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

     

    208.67.222.222

    208.67.220.220

     

    (There may be better or faster DNS numbers in your area, but these should be a good test).

    Click OK.
