We're building a new farm:
3 Windows 2008 R2 X64 machines
I've generated a MachineKey and applied it in IIS 7.5 Machine Key section.
Do I use the same MachineKey values for .NET 4.0?
Or Do I have different Keys for 2.0 and 4.0?

Yes, the HashKey is the same for both web.configs. The key is at the SERVER level.
"I've generated a MachineKey and applied it in IIS 7.5 Machine Key section."
> Good, Take the validation and decryption Keys and paste them into your <machinekey validationkey and decreptionkey locations>
Do I use the same MachineKey values for .NET 4.0? Or Do I have different Keys for 2.0 and 4.0?
> Yes. It is a SERVER Level key. It has nothing to do with the version of .net.
