Windows 10: I lost access to my external server when laptop updated to Windows 11.

I lost access to my external server when laptop updated to Windows 11. Cannot reconnect it and it has vital information. Windows "help" states it cannot repair a device connected from a network. I do not want to uninstall the server because it has loads of vital information that I do not want to lose and do not have stored anywhere else. HELP!!

Microsoft Prepares Update for Windows Home Server

Microsoft's Windows Home Server officially launched earlier this month, is already preparing to be updated. Microsoft says that the new update is "part of the ongoing process of continually enhancing the customer experience with Windows Home Server." The update includes a few feature additions for Windows Home Server. Currently, users who login to their server when away from their home network - through an external URL like https://yourname.homeserver.com - are greeted with a security warning. The November 27 update will now provide users with a trusted SSL certificate for their Windows Home Severs. The SSL certification was provided with the help of Windows Live Domains and GoDaddy. Other new features include a "Delete All" button to remove home computer backups. Microsoft has also taken steps to make the Shared Folders and Server Storage aspects of Windows Home Server more robust and user friendly.

Remote access to my (local) server's folders

I am running a simple local fileserver. Windows based.

I would like to access (load, save, modify) what's on this server when I am away on business trips. Laptop -- internet -- router - server

What is the best way to do this? Setup WebDAV or ftp-server or something else? I would prefer direct access, ie. being able to load/save from an application rather than using ftp as a separate step.

 

Remote access to my (local) server's folders

But what if he tries to access this mapped drive when he is not on the same subnet of his server ?
