Azure AD Connect install issues

    Question

  • Hello All

    I've come into an issue trying to install Azure AD Connect into a client environment. Install fails on 2 different servers at same point every time. "Unable to install the Synchronization Service. Please see the event logs for additional details"

    Sync Engine logs below, ADSync service exists. I've just inherited this domain so may be something in the back group which I've not been able to spot yet.

    PLEASE HELP!
