DFS Replication

[Chris]

I have two Win 2003 server boxes, one of which contains a
very important file share called 'si'. I created a DFS
root and added a second Root Target - the idea being to
replicate the data from sever one to server two. I
enabled replication and sat waiting for soething to
happen. Half an hour later I found that several
directories had dissappeared.

A file called Ntfrs_PreExisting_See_event_log had
appeared and I found the files had been moved to this
directory. I examined the event log to find the
following event:

Event ID 13520:
The File Replication Service moved the preexisting files
in f:\si to f:\si\NtFrs_PreExisting___See_EventLog.
The File Replication Service may delete the files in
f:\si\NtFrs_PreExisting___See_EventLog at any time.
Files can be saved from deletion by copying them out of
f:\si\NtFrs_PreExisting___See_EventLog. Copying
the files into f:\si may lead to name conflicts if the
files already exist
on some other replicating partner.
In some cases, the File Replication Service may copy a
file
from f:\si\NtFrs_PreExisting___See_EventLog into f:\si
instead of replicating the file from some other
replicating partner.
Space can be recovered at any time by deleting the files
in f:\si\NtFrs_PreExisting___See_EventLog.

As you can see this was very strange and the details in
the event log pretty worrying. What had I done wrong and
why did the directories get moved?

Hi Chris,

Thanks for posting!

Based on my research, the warning message is an expected result of a
successful completion of the FRS.

Here are the five events that should be recorded in the File Replication
Service upon successful completion of the FRS replica set subscriber
information rebuild:

Event Type: Information
Event Source: NtFrs
Event Category: None
Event ID: 13501
Date: 1/24/2001
Time: 12:30:51 PM
User: N/A
Computer: DC2
Description:
The File Replication Service is starting.

Event Type: Warning
Event Source: NtFrs
Event Category: None
Event ID: 13514
Date: 1/24/2001
Time: 12:31:16 PM
User: N/A
Computer: DC2
Description:
The File Replication Service may be preventing the computer DC2 from
becoming a domain controller while the system volume is being initialized
with data from another domain controller and then shared as SYSVOL.

Type "net share" to check for the SYSVOL share. The File Replication
Service has stopped preventing the computer from becoming a domain
controller once the SYSVOL share appears.

The initialization of the system volume can take some time. The time is
dependent on the amount of data in the system volume, the availability of
other domain controllers, and the replication interval between domain
controllers.

The initialization of the system volume can be bypassed by first typing
regedt32 and setting the value of SysvolReady to 1 and then restarting the
Netlogon service.

WARNING - BYPASSING THE SYSTEM VOLUME INITIALIZATION IS NOT RECOMMENDED.
Applications may fail in unexpected ways.

The value SysvolReady is located by clicking on HKEY_LOCAL_MACHINE and
then clicking on System, CurrentControlSet, Services, Netlogon, and
Parameters.

The Netlogon service can be restarted by typing "net stop netlogon"
followed by "net start netlogon".

Event Type: Warning
Event Source: NtFrs
Event Category: None
Event ID: 13520
Date: 1/24/2001
Time: 12:32:16 PM
User: N/A
Computer: DC2
Description:
The File Replication Service moved the preexisting files in
c:\winnt\sysvol\sysvol\domain to
c:\winnt\sysvol\sysvol\domain\NtFrs_PreExisting___See_EventLog.

The File Replication Service may delete the files in
c:\winnt\sysvol\sysvol\domain\NtFrs_PreExisting___See_EventLog at any time.
Files can be saved from deletion by copying them out of
c:\winnt\sysvol\sysvol\domain\NtFrs_PreExisting___See_EventLog. Copying the
files into c:\winnt\sysvol\sysvol\domain may lead to name conflicts if the
files already exist on some other replicating partner.

In some cases, the File Replication Service may copy a file from
c:\winnt\sysvol\sysvol\domain\NtFrs_PreExisting___See_EventLog into
c:\winnt\sysvol\sysvol\domain instead of replicating the file from some
other replicating partner.

Space can be recovered at any time by deleting the files in
c:\winnt\sysvol\sysvol\domain\NtFrs_PreExisting___See_EventLog.

Please feel free to let me know if you have any further concerns or
questions regarding the issue.

Have a nice day.
