I have been working on this issue for the past week without any success. Here's what's happening, I use Global SonicWall to VPN in, then I go through our internal firewall. Everything works perfectly until there, but then when I want to remote desktop to our Windows Server 2012 R2, I get the login window where it says "Wrong Credentials". I know they are the correct credentials, as I can use my colleague's laptop and I am able to connect fine to the server. Something must be wrong with my laptop, it is a Latitude E5470 Dell. Could it have to do with my Network Driver?
Thank you for your help. -Clemmy
