Authentication Error when accessing Sharepoint list via web service
- by Joe
I wrote a windows service a few months ago that would ping a Sharepoint list using _vti_bin/lists.asmx function GetListItemChanges. It was working fine until a few weeks ago when my company upgraded our Sharepoint instance to SP1.
Now whenever my service attempts to access Sharepoint I receive an 401.1 authentication error:
Error:
You are not authorized to view this page You do not have permission to
view this directory or page using the credentials that you supplied. Please
try the following: Contact the Web
site administrator if you believe you
should be able to view this directory
or page. HTTP Error 401.1 -
Unauthorized: Access is denied due to
invalid credentials. Internet
Information Services (IIS)
I have checked and my privileges on the site have not changed. here is the code In which I call the list:
Lists listsService = new Lists();
listsService.Credentials = new NetworkCredential("UserName", "Password", "domain");
Result = listsService.GetListItemChanges("List name", null, dTime.ToString(), null);
It has also been brought to my attention that basic authentication may have been disabled on our farm. I don't believe I'm using that but I may be mistaken.
