The function BuildPath in the Utilities\Utilities.vb file incorrectly attempts to clean the path of double delimeters - ordinarily this would be fine, except when the path is a UNC share name, it strips off the leading slash and then when methods subsequently try to use the path for file IO they end up trying to work on a local drive, since the .net framework classes interpet a path starting with a single slash as meaning the root of the local disk.

To reproduce, create a vdir in IIS and use a UNC share on a different machine as the location (I'll assume you can set up all the proper permissions for doing this), then install a portal into the vdir. Install the gallery module and drop it onto a page. The page will fail to load with a null reference exception and examining the log will show that it is trying to access a local disk location instead of the share path when it initializes the default gallery folder.

To be sure, I commented out the line "output.Replace(Delimiter & Delimiter, Delimiter)" in the function and dropped it into my portal. Sure enough, the gallery initialized without a problem.

First... you will need the source code as that file is not distributed with the regular release (get the source code from the DNN website for free)

Then, the file is located in the Components\Utilties\ directory
