You can have too much of a good thing, VMs included. The scenario is that I am at home using a Windows 7 VM running under VMWare Workstation. From the VM, I am VPN’d into the office where I am connected to my physical laptop, on which I am running vCenter. I have the console of a Windows XP machine open from virtual center but there is no way to log in to it because Ctrl-Alt-Delete just affects the local VM. Ctrl-Alt-Ins the same.
Will post a solution when I find it.
