We have some users that cannot connect to our network over Direct Access.
Common for these users is that they have Intel Technology Access Filter Driver installed (default on their Lenovo laptops)
Unchecking the driver under the NIC in use will solve the issue. (or uninstalling the driver)
There are 3000 users and afraid this will result in a lot of noise when pc's are replaced or maybe Vantage reinstall the driver.
