How do I set directory and file permissions to allow file upload?

I have a web service that accepts a byte stream from a .NET windows client
and everytime the UploadFile method I get 401 Unauthorized error from IIS
5.1.

Running on development platform where all on XP Pro, no domain controller.

When I call this code from my windows forms client

--- snip ---
Dim uriString As String =
"http://localhost/IDSM_WebService/uploads/wireless1.doc"

' Create a new WebClient instance.
Dim myWebClient As New System.Net.WebClient()
Dim fileName As String = "c:\wireless1.doc"

' Upload the file to the Url using the HTTP 1.0 POST.
Dim responseArray As Byte() = myWebClient.UploadFile(uriString, "PUT",
fileName)

' Decode and display the response.
str = "Response Received.The contents of the file uploaded are: " &
System.Text.Encoding.ASCII.GetString(responseArray)

--- snip ---

I get this error. Any ideas?

   An unhandled exception of type 'System.Net.WebException' occurred in
system.dll
   Additional information: The remote server returned an error: (401)
Unauthorized.
