Windows Explorer Hangs Connecting to Distributed File System Roots
When selecting a remote share in Windows Explorer the user interface may appear to hang for a short period and you may see the blue circle spinning during this time. This period could be up to ten minutes, after which the Explorer window will work as expected.
This issue will repeat if you reselect that folder in Windows Explorer.
This issue can occur when all of the following circumstances are true:
- The remote share is a Distributed File System (DFS) root.
- The DFS root target share is set to Files or programs from the share will not be available offline setting.
- The Windows Vista or Windows Server 2008 client has the share path UNC for that DFS root in its client-side cache.
- There are multiple DFS root targets.
This hang or delay may be longer if the DFS root targets are distributed to network locations and sites remote from the client.
