Remote access to Wyse 3030/3040

Hello, 

I have a few different types of thin clients from Dell/Wyse, such as the 3030 LT (N03D), 3040 and the 3010 Tx0 units - I'd like to be able to connect to these devices from distant locations to be able to adjust the configurations. I understand it might be possible to do this using VNC, but how exactly? Is there a guide? Do you simply need an IP address? Is there another way to connect, or is this the best way? Is SSH an option for old thin clients? I understand WMS (Windows Multipoint Server) was an option, but I'm also unsure how to use this to connect to a thin client. I was hoping to be able to get a web management interface through the browser, but it doesn't seem that's possible, although I could be wrong... 

Does anyone know about this? 

I appreciate any advice.

Thank you
