  • Active Directory Replication Issues

    Guys and gals, I could do with some advice.

    I have a small site of a couple hundered users, in the past year I have migrated from SBS 2003 to 2008 and exchange 2010.
    I have started having replication issues with one of my DC.

    I have three and the one holding all my FSMO rules has stopped replicating, with errors in DCDIAG of Server1 not responding. When I check with repadmin it tells me the target principal name is incorrect.

    Before I jump into completely messing my AD up, can anybody help diagnose the best fix.

    Its looking at this time that SERVER1 has been blocked from replicating to my other two DCs.

    Times are consistant on all servers, and when I try and connect to a share on SERVER1 I get logon failure - the target account name is incorrect.

    All help would be appreciated

    Hi,

    Can you provide AD diagram?
    If you force replication from sites and services what errors get generated in event logs.
    and
    can you run dcdiag /fix and netdiag /fix and upload the results.
    Thanks & Regards

        Hi,

        Can you upload the netdiag and dcdiag results from all 3 dc.? From this i see replication (inbound/outbound disabled), GC advertising, Time Server (stop), Netlogon Service (paused), FMSO role marked down. ..... a lot of errors

        Can you check your DNS and name resolution on windows server 2008

        You can export the command result like this dcdiag > ServerNamer.txt

        it will be easy to refer
        Thanks & Regards
