Determine whether a folder is on the local computer

My VB 2008 application has configuration files which may be stored either locally or in a server folder. However, if they're stored on the server, the issue arises that a laptop might be used when the server is not accessible. I want to have a fallback process that will determine, if the file is not found (that is, if File.Exists returns False), if it's looking for a server location; if so, I would assume that the server is inaccessible and check a secondary location for the configuration information. If we're looking at the local computer, then I would assume the file doesn't exist, either because it's a new installation or because someone wiped out the file, and I would reinitialize.

I'm not sure how to determine whether the folder location is on the local computer or a server. If it starts with a "\\", of course, that would be a strong indicator of a network location. But a drive letter other than C: is ambiguous; it could be a second physical or logical drive, or it could be a mapped network drive. Can you suggest a way to know whether it's local or network?

Hi  ElrondCT;

Have your tried using DriveInfo class to find all the drives on the local system whether they are CDRom, Fixed, Network, NoRootDirectory, Ram, Removable, or Unknown. It can also report if the drive IsReady and other information.
