  • Hi,

    You need to be  at least Windows Server 2008 DFL in your domain in order to migrate from FRS to DFSR.

    Windows Server 2008 ships a command line tool called ‘dfsrmig.exe’ which can be used by an administrator to initiate migration of SYSVOL replication from FRS to the DFS Replication service.

    try dfsrmig /GetMigrationState if its in start state then its is using FRS.

  • Hello,

    Thanks for your reply.

    I found this

    http://www.showmehowtodoit.com/2013/step-by-step-frs-to-dfsr-migration-guide-for-windows-2008-and-2008-r2/

    and while running dcdiag, I found this error:

    An error event occurred.  EventID: 0xC0002719

                Time Generated: 03/05/2014   11:22:05

                Event String:

                DCOM was unable to communicate with the computer parkex.myDomain.com using any of the configured protocols.

    The article recommends that one should migrate to DFRS if no errors found. Should I be concerned about this error?

    parkex was our old exchange server (2000), way back before I was working here. Not sure why it is still appearing in AD (and what other roles it held).

    Thanks.

  • Hi Birenc,

    You  need to do a metadata cleanup to remove all the old references from active directory. 

    Make sure that you seize the FSMO roles (if any) to your primary DC. And also Do check DNS zones and DNS zone proerties, Name server tab and AD sites and services.
