[Samba] Restoring SYSVOL Replication After S4

[Adam Tauno Williams]

I realize this is not a Samba specified quesiton... but I thought  
someone here might have some experience with this.

After migrating from an purely S4 AD domain to a purely Windows 2008R2  
AD domain one is left with no functioning SYSVOL replication (FRS or  
DFS).  This makes sense as S4 is not aware of SYSVOL replication.  So  
the question is how to bootstrap SYSVOL replication on a set of  
Windows 2008R2 DCs with everything apparently working except SYSVOL.
