2008 DFSR doesn't work anymore
Situation: The clients is running 2 Windows 2008 DCs on 2
sites. The DFSR has been working, but doesn't work any more. Here are the
details:
" DFS between 2 offices
ServerB (25Mb/5Mb)
ServerC (T1 4.5Mb/1.5Mb).
I have several folders created and just discovered inconsistency as follows.
I was logged in to B Site and both drives "\\ServerB\shared" and
"\\c\shared" had the same folder/file structure.
However when I opened "\\ServerC\d$\shared" - at least 1 folder was
missing.
DFS is scheduled to run at full speed from 9pm - 5am and 26Kb during work
hours but it has been turned off.
I had to manually synchronize it so people could work on the files. Most of
the documents are PPT files 100MB-200MB in size, when replication was
running during day, PPT docs could not be saved numerous times. for example.
1. 100MB PPT is opened and modified
2. PPT is saved
3. more modifications were made
4. Could not be saved.
I believe it was due to real time replication, however the missing
folder/different view is something I have not seen yet".
We found the following event:
In ServerB we have this Event
Source: DFSR
Event ID: 6804
Description:The DFS Replication service has detected that no connections are
configured for replication group shared. No data is being replicated for
this replication group.
Additional Information:

In the ServerC We have this event
Event ID: 4102
Description:The DFS Replication service initialized the replicated folder at
local path D:\shared and is waiting to perform initial replication. The
replicated folder will remain in this state until it has received replicated
data, directly or indirectly, from the designated primary member.

In the debug (C:windows\debug), we found some errors as shown below:

Troubleshooting: 1. Disable TCP off loading on all DFSR
replications partners.

Then reboot the server
After the reboot, both DCs get following Event:
