Do you have vcenter?  If you have vcenter you can do it through the powershell kit.

what do you mean, on one but not the other, are we talking about two different locations, or are you using the free version?

Control application downtime with dependency maps

Visualize the interdependencies between application components better with Applications Manager's automated application discovery and dependency mapping feature. Resolve performance issues faster by quickly isolating problematic components.

There are PowerCLI commandlets for starting, stopping, restarting and suspending virtual machines – Start-VM, Stop-VM, Suspend-VM, Stop-VM. The follow examples show how to use some of them:

# filtering machines by name and start those that are not started
Get-VM <name-filter> | where { $_.PowerState –eq "PoweredOff" } | Start-VM

# stopping virtual machine, defining that we do not want to confirm
# each stop operation
Get-VM <name-filter> | Stop-VM –confirm:$false

I would recommend using the following, also VMware recommends the use of PowerCLI, which is PowerShell interface with vSphere-specific additions.

http://communities.vmware.com/community/vmtn/server/vsphere/automationtools/powercli

One of the simplest PowerCLI examples, and something which is actually extremely useful on its own, is the Get-VM cmdlet. Which lists VMs.

PowerCLI can be a bit overwhelming to use,  But it can be enhanced with a nice toolset and a library of preconfigured scripts to jump-start your mass changes, which is possible with PowerGUI

http://powergui.org/index.jspa

and

It's also worth looking at The free VMware Guest Console

http://labs.vmware.com/flings/vgc

The free VMware Guest Console, an experimental application created by VMware Labs, is a great tool for managing vSphere VM processes and files. You can view, sort and kill processes across all VMs, and you can also run a script on all Windows or Linux VMs.

If you do want a script, LucD (1 of *the* premier PowerCLI gurus; literally co-wrote the book on PowerCLI :) ) provides a script in the following link:

@bharrington83 yes they are two seperate boxes (one connected to VCenter and one not), located on different networks. Neither are free versions

You can use the PowerCLI direct to an esxi server, it's just advantageous to use vcenter. As far as reverting goes, you'll need to have a snapshot running all the time,  then to revert, just revert the snapshot.
