System.IO.DirectoryNotFoundException: Could not find a part of the path

I'm trying to create a directory on the web server with a
vb.net code:
....

Dim dirName As String = "w:\filepath\images"

If Not Directory.Exists(dirName) Then
Directory.CreateDirectory(dirName)
Label1.Text = "Directory created"
Else
Label1.Text = "Directory exists"
End If

....

And I'm getting an exception:
Could not find a part of the path "w:\".

Exception Details: System.IO.DirectoryNotFoundException:
Could not find a part of the path "w:\".

When I run it with "w:\filepath\" it says "Directory
exists". Only when I want to create a new directory the
exception occurs. The ASP.NET user has all rights on that
drive, and there would be another exception
like ... "access to path denied".

Does anyone knows what is going on here and what does it
mean "could not find a part of the path"?

I can run this code locally and it works fine, the problem
is only at my webservers host computer.
