Question : Forest functional level issue when trying to install Exchange Server 2010

Hello experts,

When trying to install Exchange server 2010 on a Windows 2008 R2 Standard, I am getting this error:

The forest functional level of the current Active Directory forest is not Windows Server 2003 native or later. To install Exchange Server 2010, the forest functional level must be at least Windows Server 2003 native.

I am sure that my domain functional level is Windows 2008 R2.

My domain contains only this single DC and there is no any existing Exchange installation.

I was trying to use ADSI Edit as mentioned in this article:

But I couldn't locate (CN=Partitions), it seems that I don't have it.

Help please!
