Servers: Windows Server 2008 R2 Standard SP1.
Clients: Windows 7 Pro SP1.
Last week, as soon as KB4103718 was installed on the clients, they couldn't connect to one of our servers (error is attached here). They could connect to the other one though.
I just looked on both servers and that KB is pending, wanting to install.
Why would the behavior be different on the two machines? I want to make the second one function with RDP like it always has. My only resolution so far is to go to each clinet machine and uninstall that KB, and then disable auto updates so it doesn't get installed again, but obviously that's not a real solution.
