An unsecured or incorrectly secured fault was received from the other party
An unsecured or incorrectly secured fault was received from the other party
This error normally occurs when the Time Zone of the server and the client are different.
The remote server and the client's system time must be within 10 minutes of each other.
Solution 1:
So One Temporary solution was to change the TimeZone as well as the Time to the time currently on the server.
Solution 2:
Was to include the following security node under the binding of custom binding element.
<security authenticationMode="Kerberos"> <localClientSettings maxClockSkew="00:07:00" /> <localServiceSettings maxClockSkew="00:07:00" /> <secureConversationBootstrap> <localClientSettings maxClockSkew="00:30:00" /> <localServiceSettings maxClockSkew="00:30:00" /> </secureConversationBootstrap> </security>

Read specific nodes from an XML File
The following article discusses how to read an XML file.
The sample XML file that i have used is also attached below.
I have used XmlTextReader for reading.
The while (reader.Read()) return true until all the nodes of the document are read.
reader.ReadToFollowing("repeat_element");
is used to jump to the specified node, incase you are not interested in any other node and want to read only that node or its child nodes.
reader.Name returns the name of the element and reader.ReadString() will return its value/innerText.
