Hi Ian.
Yes, indeed, it has been quite a while.
To answer this, and all of the questions above:
<this will drive you nuts>
I am currently running my two WSeB servers in MS Virtual PC running on XP, which itself is running on ESX (under vSphere).

So at the moment I RDP into the XP host to manage the two OS/2 VM's.
So even if it's a Linux host, xfreerdp works well

So I've avoided setting up/using VNC - for now.
The thinking was to move the two MS VirtualPC's to native ESX Vm's and remotely administer them directly.
<sigh>
