Network 'acting up'??

We have tried to apply some fixes with our Symantec Antivirus causing machines to lose their network connection.

This affects computers on the entire campus.  If you are using Symantec EndPoint Protection, make sure that your machine isn't losing its connection due to False-Positive Denial of Service attacks caused by Network Threat Protection being too hardcore.  When a DoS attack is detected, the NTP shuts off access to that IP address for 10 minutes thus causing the page to time-out when loading websites

The issue may appear to be the "network being slow..." but in reality, it's just a bunch of crap running in the background making it to where you're not getting all of your packets.

We are applying this fix to the Loaner Laptops for checkout, the Sherrill Laptop Cart,... and any other office machines just sitting around on wireless and obviously any future installations.  Fun times.

Please be mindful of this fix.

This applies to any computers running Symantec EndPoint Protection v11-12.x and with Network Threat Protection installed (by default it is).
