Hi Ausgirl (and anyone having problems like this):
Can you do me a favor and let me know what your DNS Server(s) are? To do this in Windows:
Click on Start button > Run > and Type command cmd > Press [enter] key
At DOS prompt type the command:
The online line(s) I need to now are the ones that say "DNS Servers". It will look something like this:
DNS Servers . . . . . . . . . . . . . : 18.104.22.168
I do think its intermittent DNS issues that is causing this, but as far as I can tell our server is performing at 100%.
