DC is not in the domain controller's OU

[Regamoks]

I got problems with my DC and ran DCDIAG which reported a problem i don't know how to fix:

Starting test: MachineAccount

Checking machine account for DC DC2 on DC DC2.
* The current DC is not in the domain controller's OU

The account DC2 is not trusted for delegation. It cannot replicate.

The account DC2 is not a DC account. It cannot replicate.

Warning: Attribute userAccountControl of DC2 is: 0x1000 = ( WORKSTATION_TRUST_ACCOUNT )

Typical setting for a DC is 0x82000 = ( SERVER_TRUST_ACCOUNT | TRUSTED_FOR_DELEGATION )

This may be affecting replication?
