I attempted to do a Find in DOpus through a network UNC path (the machine is using DFS) and I couldn't get it to search from the machine name. Rather I had to search from machine-name \ directory.
Repro steps:
Create a Samba / MS networked share (you'll probably need a Win2K3 server)
Activate DFS and create a mapping to "SomeVirtualDirectory"
Drop a file in SomeVirtualDirectory called SomethingOrOther.txt
On a client machine with DOpus installed open a lister, click in the location bar and type the UNC path to the machine \YourMachine
Hit CTRL-F
In the Find-In text-box type: \YourMachine then click "Add Folder"
Try and do a search for SomethingOrOther.txt
Results: It doesn't locate the file.
In the Find-in text-box type: \YourMachine\SomeVirtualDirectory and click "Add Folder"
This isn't really a bug; the machine name is not a real folder and the Find tool only searches in real folders.
If you want the ability to search from a machine name, enumerating all of the public shares in turn, then you should send GPSoftware a feature request.
This tells customers that DOpus does at a minimum what explorer does and, for the most part, better. If DOpus doesn't do what explorer does it's a bug, because it's failing to live up to the most basic expectation of the product.
