    Scenario

     

    We have a windows XP Client which is calling a .net 2 Web Service which uses WSE 2.0 SP3 on a remote Windows 2003 Server.  When we make the call we get the following error message:

     

    "System.ApplicationException: InitializeSecurityContext call failed with the following error message: A specified logon session does not exist.  It may already have been terminated."

     

    We only get this message when calling our web service from a client running Windows XP Service Pack 2.

     

    Symptoms

     

  1. You will get the following message in the event log.

     

    The Security System could not establish a secured connection with the server ldap/<DomainController>.<Domain>/<Domain>.  No authentication protocol was available.

     

  2. When a windows 2003 client is used to make the same call it works fine.

     

  3. We had other projects doing the same thing which were working okay.  These other projects were using the same build of XP Client

     

     

    Work Around

     

    There is a workaround to this problem, when you log off and back on everything starts working again.

     

    Solution

     

    The following article describes more on this problem, there is also a hot fix which has been used by some of our developers.  This seems to have stopped their problem.
