Symptom
There is a shared folder (Share) on a DC of contoso.com. If you access the shared folder using the path\\contoso.com\Share, you will find the shared folder is empty. If you try to create a new folder in \\contoso.com\Share, you will get an error“Could not find this item. This is no longer located in contoso.com. Verify the item's location and try again”.

However, you can create a new folder in\\Controller\Share or\\Controller.contoso.com\Share without issue (Controller is the server name). The NETLOGON and SYSVOL shares are not subject to this error.
Cause
Mapping a drive to the domain name is reserved for DFS. The SMB client will connect to IPC$ and get a list of DFS namespaces. If DFS has not been setup there is nothing to refer, thus the blank“folder.”
When using the controller name, either short or FQDN, it establishes a normal SMB share connection. This is why you can create folders through explorer.
Solution
You must create folders/share on the DFS root through the DFS Management tool, or via CMD/PowerShell. You cannot achieve this via Windows Explorer.
Please refer to Figure 2 and Figure 3, create a DFS domain-namespace namedShare, then you can create a new folder in \\contoso.com\Share.
