Problem before change domain controller

Sorry, bad Write-English, but good Read.

Input:

1) AD enviroment (AD authorization, no SSO)

2) Change hostname DC and forest/domain level Windows 2003 Native (hosts x86) -> Windows 2008 R2 (hosts x64).

3) Before point 2 in SD+ (v7.6) not working domain authorization.

4) I have tried to solve the problem as in the FAQ - reset local admin account & change hostname DC, but AD-authorize local authentication is disabled.

5) I try edit database (MS SQL 2005) for change hostname DC - ок, but in SD+ appeared +1 domain (domain name is rigth, but old domain name is NetBIOS-name (corp), new - DNS-name(corp.local)).

6) AD syncronization - not good, only Users container is visible, other OU and containers - no.

Output:

How do I solved this problem(s) ?
