Problem installing Exchange 2013

Hello.
My Exchange installation stops at 97% (Mailbox role: Transport service) with the following message:

Error:
The following error was generated when "$error.Clear();
          $maxWait = New-TimeSpan -Minutes 8
          $timeout = Get-Date;
          $timeout = $timeout.Add($maxWait);
          $currTime = Get-Date;
          $successfullySetConfigDC = $false;

          while($currTime -le $timeout)
          {
            $setSharedCDCErrors = @();
            try
            {
              Set-SharedConfigDC -DomainController $RoleDomainController -ErrorVariable setSharedCDCErrors -ErrorAction SilentlyContinue;
              $successfullySetConfigDC = ($setSharedCDCErrors.Count -eq 0);

              if($successfullySetConfigDC)
              {
                break;
              }
              Write-ExchangeSetupLog -Info ("An error ocurred while setting shared config DC. Error: " + $setSharedCDCErrors[0]);
            }
            catch
            {
              Write-ExchangeSetupLog -Info ("An exception ocurred while setting shared config DC. Exception: " + $_.Exception.Message);
            }

            Write-ExchangeSetupLog -Info ("Waiting 30 seconds before attempting again.");
            Start-Sleep -Seconds 30;
            $currTime = Get-Date;
          }

          if( -not $successfullySetConfigDC)
          {
            Write-ExchangeSetupLog -Error "Unable to set shared config DC.";
          }
        " was run: "Unable to set shared config DC.".


There is some articles in the Internet related to the same message, but the problem always turn out to be related to IPv6 being disabled on the DC.


This is my servers:

server 2008R2 doman controller (AD 2008R2 level, two sites but all servers are in site 1)
server 2008R2 exchange 2010 with all updates and SP3 (CAS and MBX role)
server 2012 on witch i try to install exchange 2013 (CAS and MBX roles)

-  All servers has the AD and link layer topology service running
-  All servers are updates
-  All servers are able to ping each other on private IPv6 adresses (manual, no gateway on ipv6)


The event log on the exch2013  server gives these two interesting messages:

Message 1:

Microsoft.Exchange.Directory.TopologyService.exe
   5188
   bjarnessen.local
   No Suitable Directory Servers Found in Forest bjarnessen.local Site Hjellestadvegen234C.


MESSAGE 2:

I believe that the event log messages is related to the problem here, but i have no clue where to go from here.

I appreciate all help here.
Thanks!
