    Guys, solved the problem!

    the child domain that had been relegated was still on the parent domain tree. By removing all remnant from the deleted child domain, synchronization with ad connect has been resolved.

    Thanks for the help guys!

    Looking at the error there seems to be a problem retrieving to Active Directory Schema. Make sure you are running the wizard using credentials of Enterprise Admin account. If it still fails, try below steps:

    1. Run nltest /dsgetdc: and take a note of the DC name.
    2. Run regsvr32 schmmgmt.dll cmd to register AD Schema binaries.
    3. Run mmc > File menu > Add/remove Snap-in > Active Directory Schema.
    4. Right click on Active Directory Schema and click on Change Active Directory Domain Controller and select the DC that was returned in step 1.

    If this also fails, please investigate why you are unable to connect to AD Schema. This can be due to network connectivity issue. Also consider reviewing the trace log that is generated under C:\ProgramData\AADConnect folder.
