  • You access a Distributed File System (DFS) share through a nested DFS link from the computer.
  • You open the Properties dialog box to find previous versions of a file or of a folder in the share.
In this scenario, you receive the following message:
No previous version available.
However, you can find previous versions if you access the DFS share by using \\<servername>\<sharename>.

The following is a sample scenario of the nested DFS link:
  • There are two domain-based DFS namespaces: \\<DomainName>\<DFSRoot1> and \\<DomainName>\<DFSRoot2>.
  • \\<DomainName>\<DFSRoot1>\<LinkA> is a DFS link that maps to \\<DomainName>\<DFSRoot2>.
  • \\<DomainName>\<DFSRoot2>\<LinkB> is a DFS link that maps to the following shared folder: \\<servername>\<sharename>.
  • You access the share folder through the following DFS path: \\<DomainName>\<DFSRoot1>\<LinkA>\<LinkB>.
In this scenario, you cannot find the previous versions of a file or of a folder in the DFS share. However, you can find the previous versions if you access the share by using \\<servername>\<sharename> or \\<DomainName>\<DFSRoot2>\<LinkB>.
