\viewkind4\uc1\pard\lang2052\f0\fs20 Hello Marek,
\par
\par From your description, you're getting the following exception when consuming a certain webservice on a partiuclar client machine, correct?
\par
\par >>>>>>>>>>>>>>
\par System.Xml.XmlException: There is an unclosed literal string. Line 1,
\par <<<<<<<<<<<<<<
\par
\par Based on my experience, such exception is normally caused by some parameters passed in webmethod contains invalid string. For example, when you directly pass string parameter that contains XML reserved characters(such as < > & ), it will make the SOAP xml message corrupted. Here is a web thread discussing on this:
\par
\par http://forums.microsoft.com/msdn/showpost.aspx?postid=14221&siteid=1
\par
\par Also, from your test, you mentioned that the error occured even before soap extension be able to log the message ,correct? That means the problem occurs at the very begining (at client) when the runtime try parsing the serialized soap XML content. Based on the code snippet you provided, the webmethod's signature is as below:
\par
\par ==============
\par HelloWorld(HelloWorldRequest helloWorldRequest)
\par ==============
\par
\par So the only possible cause if the HelloWorldRequest class(regardless of any environment &platform problem), would you provide detail definiation of this body class. And is that particular problem client always pass some particular string data into the HelloWorldRequest instance?
\par
\par In addition, for that problem machine, you can check its .net framework version and latest service pack install status, compare it with other working client to see whether there is any difference.
\par
\par Please feel free to let me know if you have any other finding on this.
