**Make sure you write down any original DNS addresses to remember them for later once this problem is resolved**
These are the Win7 temporary fix instructions:
Go to Control Panel->Network & Internet->Network and Sharing Center->
Top left click on "Change adapter settings"
Right click LAC and then click properties
Click (TCP/IPv4) and then click the properties button underneath
At the bottom under DNS, click on the "Use the Following DNS server addresses" radial button
and put this in:
Preffered 8.8.8.8
Alternate 8.8.4.4
click OK and you should be good.
