Azure AD Connect migration error

Question

Hello,before we proceed to debug, I just want to say I read multiple forums and tried many things before I reached out here.

https://adminwebservice.microsoftonline.com/provisioningservice.svc

https://adminwebservice.microsoftonline.com/

adminwebservice.microsoftonline.com/

My AAD (Entra Connect Sync) migration doesn't work.

1. I disabled the IE Enhanced Security Configuration so I could log-in to microsoft account pop up
2. I disabled proxy in Windows proxy settings.
3. Windows Server version is 2022
4. I added these to Trusted sites (internet options):
   https://login.microsoftonline.com, https://aad.portal.azure.com, https://graph.windows.net, https://login.microsoftonline.us, https://.msocdn.com, https://.microsoftonline.com
5. Made sure HTTPS & HTTP is working, port 443, 80
6. No proxy in company - so we going directly
7. Enabled TLS 1.2. on the server
8. Exported configuration from previous AAD connected and have successfully imported to Entra Connect Sync (without completing the wizard)
9. Choose the same User-sign in as the server migrating from.
10. I always keep single sign on checked.
11. ! There's no DC (active directory module) on either of the servers, but ping to the DC works from both servers (connectivity)
12. I'm using the same active directory user for wizard (Use existing user, not create new user) which should be no issue, since the user is from the previous server, same permissions.
13. The error I can't understand is in the screenshot, after all the deployment steps are completed. -> Told to click install and enable staging mode.

Any ideas will be much appreciated.

Hi @Čako Martin

If you are using a proxy for EntraConnect server to access to internet you have to add it in machine.config file as mentioned in this article:

Hi @Čako Martin

Thank you for reaching us!

I understand that you are unable to configure the Entra connect tool, and you are getting an error related to Azure Service Connectivity Failed. Unable to proceed.

This might be the issue with the .NET Framework can you please check the .NET Framework the minimum .NET Framework version required is 4.6.2, and newer versions of .NET are also supported. .NET version 4.8 and greater offers the best accessibility compliance.

Update the .Net Framework and check the all the Installation prerequisites and re-install the Entra connect tool and see if the issue is fixed.

Hope this helps. Do let us know if you any further queries by responding in the comments section.

Thanks,

when you are configuring the Entra connect tool you got the below

Solution:

you have fixed the issue by adding https://secure.aadcdn.microsoftonline-p.com to the trusted sites. I checked versions and everything was up to date. We don't use proxy, so I edited the C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config to <system.net> AI ConvertCopy

`**<defaultProxy enabled="false" />**
`

</system.net>
