Dcdiag test failed on VerifyEnterpriseReferences

I just upgrade 2003 Active Directory to 2008 version.
My 2008 Active Directory environment is just a single domain controller
Every thing seems to be fine.
After I execute dcdiag testing.
There is a failed test on VerifyEnterpriseReferences.
Follow is the error description :
