[dba-Tech] X Server (X11) for Windows

Hi all

I need an X Server for Windows. For Macs you can download one from
Apple for free:

but I cannot find a free one for Windows.
However, MI/X:

is available for USD 25, so we are not talking about big
money, but perhaps someone knows a free alternative?

It if for accessing an app running on the NeTraverse Win4Lin Terminal
