    Plus is the zone transfers set correctly so the correct servers get the dns transfered to them.

    You can have just Dynamic Updates, but I agree Secure Updates are better. For those that don't know, Secure Updates basically means only authenticated clients in the domain can make changes to DNS. This stops any external or rogue devices messing your DNS setup!

    Again, like Zone Transfers, Secure Updates has to be specified on the Forward and all Reverse Lookup Zones in turn.

    @Michael
    Yes I enabled zone transfers on both servers for forward and reverse look up zones
    The 2K3 server is the role holder for all FSMO's
    The 2K8 Server is a GC

    Ive just set the IP DNS config to your recommendations (the 2k8 server was pointing to the 2k3 as primary DNS)


    @ricki
    The dynamic updates was secure - Ive reduced it to none secure (grasping at straws now)
    Zone transfers is set to all DCs
    Dcdiag on the 2k3 server doesnt return any errors.

    The repadmin on both servers says successfull or all items

    Thanks both for your help, please keep the ideas coming.

    just to add

    Both servers have their firewalls disabled, and there is no SYSVOL share on the 2k8 server

    FIXED IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    I *think* doing this has fixed it Using the BurFlags registry key to reinitialize File Replication Service replica sets (I tired this on Monday and it didnt work)

    DCdiag doesnt list any more errors!, the SYSVOL is there!

    Hopefully it will stay working

    Thank you everyone for your help and support, its been much needed!

    Good job, glad you got it sorted. The last time I used Burflags was between a 2000/2003 server, many moons ago!

    I know it's old but this really helped me out today. I had to set the current primary DC to burflag D4 and the new one to D2.

    Normally setting the existing FSMO DC to 'D4' should be suffice as it becomes authoritative above everything else. You only need to use D2 if the other DC wouldn't play ball after this. Even in a small environment, it can take a good 30 mins or more to re-build and replicate out.
