so I'm a bit overwhelmed/bewildered by the whole concept of networking/remote-desktop , etc.

The context is that - in my company I need to access a remote database. The standard way I use is to first connect using a VPN-Client( called Shrew Soft Access manager), then once that says:

"network device configured
tunnel enabled"

I'm good to connect using windows "Remote Desktop Connection" .

But now our company set up an Amazon AWS database, and I'm told I need to connect, and I ony need to use RDP. So I tried the standard windows one - but it doesn't work.

On wikipedia , I looked up remote desktop sftware and downloaded one called VNC Viewer. but it doesn't work.

Any advice/tips/comments appreciated

EDIT: YAYA! I finally got a little more connected . I had to use my username as a fully qualified name:

Computer: XYZ.XYZ.XYZ.XYZ

USERNAME: XYZ.XYZ.XYZ.XYZ\aazzam
