Hello Can you check IPV6 is enable or disable ? Enable it and try installing all the windows updates and re-run the setup. Thanks Mhussain

IPv6 is enable

Hi, If your IPV6 is enabled, this might be other issue. I suggest you follow Jonas’s suggestion to paste the related information of your installation log. It can be found in this path: The system disk\ExchangeSetupLogs\ExchangeSetup You can follow this document to check the setup logs: Exchange 2007 setup logs and how to use them to troubleshoot setup http://msexchangeteam.com/archive/2007/05/07/438433.aspx Thanks, EvanPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
