SBS 2011 Migration - Active Directory replication is taking longer than expected

If you encounter this message during setup: “Active Directory replication is taking longer than expected”, do this:

Active Directory replication is taking longer than expected. You can choose whether to continue waiting.
If you choose not to wait, the migration may fail. Unless you are sure that replication is working correctly, it is recommended that you continue waiting.
Do you want to wait for the replication to finish? (Yes/No)
Most Common Cause: You will only get this dialog after the SBS setup has waited for 25 minutes and the new server has not been able to properly contact the source DC to initialize the file replication service (FRS), this is preventing the new server from becoming a domain controller. Clicking No on this dialog will almost certainly mean a failed setup. The source server is most likely in journal wrap or having FRS issues.
Resolution Summary: 
Correct the FRS issues on the source server, do not reboot the new server or close down the setup, leave the popup dialog open while you troubleshoot, once the FRS issues are corrected on the source server, you can open a command prompt on the new server by using Shift-F10 and restart the Netlogon and FRS services, then confirm that SYSVOL and NETLOGON are shared on the new server by using NET SHARE, only then you should click Yes to continue waiting, after 5 minutes the setup will go on.
