Hi All, I am hoping that someone might be able to help with an issue I am having with the Lists.asmx web service. I am seeing an intermittent unauthorized access exception that is thrown when I try to access the web service.
I am using the following code:
XmlDocument xmlDoc = new XmlDocument();
XmlNode queryXml = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "");
queryXml.InnerXml = "<Where><And><Neq><FieldRef Name='ContentType' /><Value
Type='Choice'>PIIPFolder</Value></Neq>" +
"<Eq><FieldRef Name='Editor' /><Value Type='User'>" +
HttpUtility.HtmlEncode(thisWeb.CurrentUser.Name) +
"</Value></Eq></And></Where>";
XmlNode fieldsXml = xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "");
XmlNode optionsXml = xmlDoc.CreateNode(XmlNodeType.Element, "QueryOptions", "");
optionsXml.InnerXml = "<ViewAttributes Scope='Recursive' />";
mossListService queryService = new mossListService();
queryService.Url = thisWeb.Url + "/_vti_bin/Lists.asmx";
queryService.UseDefaultCredentials = true;
string position = null;
line 157: XmlNode res = queryService.GetListItems("Pages", null, queryXml,
fieldsXml, null, optionsXml, thisWeb.ID.ToString());
on the highlighted line 157 the following exceptions are observed in this order:
line 157: A first chance exception of type 'System.Net.Sockets.SocketException'
occurred in System.dll
Additional information: No connection could be made because the target machine
actively refused it
line 157: A first chance exception of type 'System.Net.WebException' occurred
in System.dll
Additional information: Unable to connect to the remote server
line 157: A first chance exception of type 'System.Net.WebException' occurred
in System.dll
Additional information: Unable to connect to the remote server
line 157: A first chance exception of type 'System.Net.WebException' occurred
in System.dll
Additional information: The remote server returned an error: (401) Unauthorized.
This only occurs sometimes and refreshing the page will usually correct it.
Thanks again for your help
Roger
