VBS Programmatic logon to Project Server 2003

[Antonio Valle]

Hello!

I'm trying to access to a Project Server to use PDS, but no way when trying
to to it from a VBS script.
Here is my sample code:

----------------------------------
dim oSOAPClient
dim oXMLDocument

verbosity = 3
sURL = "http://projectdemo/projectserver/LgnIntAu.asp"
Set oXMLDocument = createObject("Msxml2.DOMDocument")
wscript.echo oXMLDocument.Load(sURL)

----------------------------------
This always returns -1

Any hint?
Thanks!!
Antonio
