File upload with vb.net

[nickin4u]

I am trying to upload a file with vb.net application using the following code.
The upload_file.php is at my website and if i try to use it through an html page on my website it works perfectly fine. This same code also used to work till sometime back but now it gives me same error all the time.

Dim strURL As String = "http://www.website.com/upload_file.php"
Dim myHTTPRequest As New System.Net.WebClient()
Dim myHTTPResponse As Byte()
myHTTPRequest.Credentials = New System.Net.NetworkCredential("username", "password")
myHTTPResponse = myHTTPRequest.UploadFile(strURL, "POST", "c:\file.jpeg")

ERROR:

"An unhandled exception of type 'System.Net.WebException' occurred in system.dll

Additional information: The remote server returned an error: (406) Not Acceptable."

I use visual studio.net 2003, i have tried this code with and without credentials (earlier it used to work without credentials) but have not been able to resolve the problem.

Any help is appreciated.
