Getting this error while Repadmin /Syncall "The encryption type requested is not supported by the KDC"

    Question

  • Hi,

    I have single domain environment with 2008 domain controllers, Now I am planning to add new Additional Domain Controller having Server 2012. Schema upgrade is done. Current Schema Version is 56 on FSMO holder running on 2008 standard.

    Other details

    Forest Functional Level - 2003

    Domain Functional Level - 2008

    PDC OS - 2008 (No issues)

    Old ADC OS - 2008 (No issues)

    1 New ADC - 2012 (Issue)

    ISSUE:- I have promoted new ADC having 2012 OS, all partitions were replicated, but after 4-5 days, it started giving following error.

    C:\Windows\system32>repadmin /syncall
    CALLBACK MESSAGE: The following replication is in progress:
