I'm hoping someone out there can shed some light on this for me...I've been using System.XmlDocument.Load(string filename) to open some Infopath docs and read some of the elements in there and get data that I need. The format of the string name is UNC and I've had no problems with this before. Now after upgrading to .NET Framework 2, I'm getting a 'System.IO.IOException: The network path was not found' error. Unfortunately I don't have physical access to the server but I'm pretty sure that nothing has change on that side of things. I'm able to open the files and browse the share where they are stored through Windows with no problem. Within my code I'm even able to use System.IO.File and System.IO.Directory to get the file names and access their properties, I just can't open them consistently with System.XmlDocument.Load (the problem comes and goes which it makes it even more annoying.) Anyone out there seen this before? I've tried sending streams instead of string file names and I'm still having trouble.
