MachineKey in Web.Config

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?

Thanks

Hi,
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.
Take a read here. http://msdn.microsoft.com/en-us/library/w8h3skw9(v=VS.80).aspx
ex:
<machineKey
    validationKey="32E35872597989D14CC1D5D9F5B1E94238D0EE32CF10AA2D2059533DF6035F4F"
    decryptionKey="B179091DBB2389B996A526DE8BCD7ACFDBCAB04EF1D085481C61496F693DF5F4"
/>
