When you try to connect with GlobalProtect you recieve the following error:
"The virtual adapter was not set up correctly due to a delay. GlobalProtect will try again soon. If the issue persists, try restarting your system" 
In the end the issue will never resolve it self and restarting doesn't work either.

Recently had to install MS SQL on a Windows Server Core installation. No GUI to manage the firewall and I can't ever for the life of my remember the commands or ports used.

if no proper acceptation or training is provided to users, users will create a lot of folders in folders and very long file names without realizing that Sharepoint/Onedrive has it's own limits and so does Windows.
Result is that files synced in OneDrive from a Sharepoint Site will not open due to the lenght of it exceeding the 255 character limit. 

For some reason my employer bought a bunch of licenses and had a bunch of VM's build but only 10% of it got used per day at peak times. Because some VM's never get booted up they basically stopped reporting to AD and connecting to the network proves troublesome causing to the VM's to show as unregistered in Citrix Studio and users can't use the VM's at all.
