Sysvol DFS-R Migration Hung

$

Hello,

We're using the process outlined in the Migrating SYSVOL to DFS Replication whitepaper (http://go.microsoft.com/fwlink/?LinkId=150375) to migrate from FRS to DFS-R in our Windows 2008 domain.  All our DCs (11 total) are Windows 2008 SP2 servers (not R2).  We kicked off the commanddfsrmig /SetGlobalState 1 on the PDC emulator.  The process copied the SYSVOL correctly to all the DCs. 

When it attempted to create the replication links, it never completed to thePrepared state.  If I run the dfsrmig /getglobal state, this is what returns.  It has been hung in this state for a few days.

The following Domain Controllers are not in sync with Global state ('Prepared')

Domain Controller (Local Migration State) - DC Type
===================================================

AD1 ('Start') - Writable DC
DC1 ('Preparing') - Primary DC
DC2 ('Preparing') - Writable DC
DC3 ('Preparing') - Writable DC
DC4 ('Preparing') - Writable DC
DC5 ('Preparing') - Writable DC
DC6 ('Preparing') - Writable DC
DC7 ('Preparing') - Writable DC
DC8 ('Preparing') - Writable DC
AD2 ('Waiting For Initial Sync') - Writable DC
DC9 ('Waiting For Initial Sync') - Writable DC

The server in question is AD1.  AD1 is in the same site as DC1.  Below is an entry from the Ddfr log on AD1. 

20130622 07:20:53.576 5768 SYSM   606 [ERROR] Migration::SysvolMigrationTask::Step [MIG] Failed Migration task. Error:

I also noticed this error in the log:

20130622 13:05:04.445 1600 CXML  2716 [ERROR] Config::XmlReader::ReadVolumeConfig Failed to Open() rKey:System\CurrentControlSet\Services\DFSR\Parameters\Volumes Error:[Error:2(0x2) BaseRegKey::Open regkey.cpp:165 1600 W The system cannot find the file specified.] 

The registry container above does not exist, although it does on DC1.

On DC4 (a DC in another site), I see the following in the logs.  This appears to be the "overlapping I/O operation in progress"

Is it possible that another DFS-R problem is keeping our DFS-R migration from occurring??

Thank you.
