Occasional Visitor

Hi

I`m trying to run the exchange 2016 CU 19 and in the stage of "preparing Organization" I get these errors:

Error:
The following error was generated when "$error.Clear();

proper command to run prepareAD is
Setup.exe /PrepareAD /OrganizationName:"<organization name>" /IAcceptExchangeServerLicenseTerms

Your command is missing /OrganizationName parameter.
re-run with /OrganizationName and check.

If the above does not work then follow below article and got to section "Repair the Exchange 2007 Security Groups" which is right at the bottom and use LDP tool to remove otherwellknownobjects from ADSIEDIT.
