We use Azure VM's without issue. I remote into them just fine.
We set up a local server on the same network as our office, running server 2012, quad core, 16GB ram etc.
For some reason, RDP runs very slow from my desktop PC, but not on my colleagues right next to me.
My PC ---> Azure VM (Works just fine)
My PC ---> VPN ---> Clients servers (Works just fine)
My PC ---> Local Server (Very slow and freezes)
Other Local PC ---> Local Server (Works just fine)
I cannot work out what could be causing these issues.
I have reinstalled my graphics driver, as well as put all settings on the lowest possible. No change.
