also make sure you type in the FQDN suffix i.e. "contoso.com" or "contoso.local" not just "contoso"

Set-AdForestMode -identity contoso.com -forestmode Windows2008R2Forest

Set-AdDomainMode -identity contoso.com -domainmode Windows2008R2Domain

Make sure that you are running above commands from elevated active directory powershell module on 2012 DC with enterprise and domain admins account in forest root domain

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

also you need to use "Windows2008R2Forest" not "Windows2008Forest"

identity is fine, http://blogs.technet.com/b/infratalks/archive/2012/12/11/step-by-step-guide-to-lower-active-directory-functional-level.aspx

When it is saying resource unavialalbe, is that referring to one of your DCs?

Thanks

Mike

All of you had correct answers, but the problem was I was attempting to change levels on a secondary DC. Apparently it didnt like that. When running commands from the primary, it went through without any problems.
Thanks for the prompt responses.
