Event ID 4625
Hello, I have a question about Error 4625 which starting to show up. I haven't found any solution yet. The error looks like someone trying to logon via account name and domain from another virtual machine in the same network via RDP, cause account name, and account domain is from this other Virtual. The only hint I have is that this is repeating every 16 minutes. It's still going even I am not logged on that virtual. So someone stole account name and trying to logon different virtual in that network or can it be some app running in the background ? Thank you
