Hi,
Just a heads-up: it looks as if vSphere 4.0 (the VMWare client application used
to administer VMWare servers/clusters) stops working on Windows XP (and perhaps
other OSes) when this month's updates are installed. I haven't confirmed this
as the definite cause of the issue I'm having, but it's the most likely suspect.
Based on a KB article about a similar issue relating to Windows 7, I suspect
that vSphere 4.0 update 1 won't be affected. But if you use vSphere, and don't
have update 1 yet, you may want to hold off on this month's updates until you
can check whether this will affect you.
Harry.
