Error 80074e46 intalling TMG

Hello I have a virtual Windows 2008R2 updated and joined to a Domain. As Domains controllers I have two Windows 2012.

When I try to install the TMG forefront in the windows 2008R2 I have "error installing ADAM \r \n (0x80074e46) .

I can ping the Ip and Name of the Domain Controllers. I can ping too the Domain name.

But if I try this:

nltest /SC_QUERY:DOMAIN.local

I get:

And If I try this:

I get:
