Windows Search may fail if you search a network folder from the toolbar in the Windows Explorer while offline on a computer that is running Windows Vista or Windows Server 2008
Consider the following scenario. On a computer that is running Windows Vista or Windows Server 2008, you enable the Always Available Offline setting. Additionally, the offline files in the network folder are synchronized to the cache of the local computer.
If you start a search for the network folder from the toolbar in Windows Explorer when the computer is offline in this scenario, Windows Search may fail. Specifically, no result is returned. However, if you start the search by clicking the Start button, the network folder is successfully found.
This issue may also occur if the network folder is hosted on a non-Windows-based server.
