We are getting a yellow exclamation mark on our network icon and MS Office 365 says we aren't connected to the internet but we do get internet without any problems. We have tried the disabling of IPv4 TCP and UDP offloading with no joy. We have tried manually entering an outside DNS, no joy.
I am not sure what this is actually looking for. Some of the machines on the network show this and some don't. All machines are clones of each other.
