Hi @Nicolas ,

1.The error 0x80072ee7 which means your SCCM server(***.dns:80) could not be resolved from the client. Are there multiple DHCP servers in you environment? I have also encountered the same error before and it came out that my client refer to the wrong DHCP server which is responsible for resolving IP address in another domain. After I turned off the wrong DHCP server, the issue resolved and the OS deployment completed successfully. So it's recommended that you check the DHCP servers and network settings in your environment to see if it is configured correctly.

How To Quickly Solve the SCCM Task Sequence Error 80072ee7
Note: This is non-Microsoft link, just for your reference.

2.May we know if the clients are in the same subnet/VLAN to the DHCP server and the PXE-enabled DP? If there are in different subnet/VLAN, you need configure IP Helper to make the PXE work well.

3,As @Rahul Jindal mentioned. Please also make sure there is no time sync issue between the client and MP/DP. For troubleshooting purpose, we can create a new task sequence or media to have a try. Similar thread for your reference:
SyncTimeWithMP() failed. 80004005

Thanks for your time. Have a nice day!

Best regards,
Simon

    80072ee7 = The server name or address could not be resolved

    So.... Check the Server name and DNS.
