Dir function on network path not working?

I want to determine if a network path exists and if it doesn't I want to create the path. For some reason the Dir function returns "" even if I give it a valid path.

example:

There is a path on my network called - \\wawa0\csio\jamie

if I do ? dir("\\wawa0\csio\jamie",vbdirectory)

or anything else... I get ""

Help?

very helpful!!! Thanks a bunch!
