Hi,
I was wondering if you prefer an equivalent software because Remote Server Administration Tools for Windows 7 only support Windows Server® 2008 R2, Windows Server® 2008, or Windows Server® 2003 instead of ESX?
I am sorry it seems Microsoft and VMware ESX are not getting alone well with each other.
You can check if the IBM Director Director and IBM Remote Deployment Manager RDM is suibable for you.
