WCF Exceptions - Time Out and Security Negotiation

Posted By:      Posted Date: October 12, 2010    Points: 0   Category :WCF

Hi All,

I am working on an application and am stuck on a snag here, hopefully someone with a geeky mind than mine could pull me off from this.

Basically the scenario is there is Windows Workflow set on a SharePoint Doc Library, which runs on any new item created. The workflow communicates with a WCF Webservice to associate Metadata to the new item created.

So when a new item is created, the workflow runs and talks to the WebService, which in turn returns the associated Metadata information from queries running on an oracle database.

I am pretty sure that my WCF Webservice has throttling set and I will probbaly start there.

Here are a couple of exceptions being thrown:


The request channel timed out while waiting for a reply after 00:02:00. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding.


Client is unable to finish the security negotiation within the configured timeout (00:02:00).  The current negotiation leg is 1 (00:02:00).


I am starting to look into the WCF Throttling settings and see if that would help me out in my quest. But anyone out there who has experienced these issues and resolved them without comprising performance (by increasing the TimeOut in Bindings), would be greatly appreciated, if they could share

WCF The Security Support Provider Interface (SSPI) negotiation failed


I am using a wcf service that I created, when both hosting machine and the client machine are on the same domain everything works just fine. When I publish the client app to the webserver in the DMZ I am getting the following error:

SOAP security negotiation with '' for   
'' failed. See inner exception  
for more details.The Security Support Provider Interface (SSPI) negotiation failed.

Here is my service main where I set up the service


 Uri baseAddress = new Uri("Http://");
      ServiceHost selfHost = new ServiceHost(typeof(QBService), baseAddress);


Security negotiation failed because the remote party did not send back a reply in a timely manner. T



Dear All i have created one simple service

Secure channel cannot be opened because security negotiation with the remote endpoint has failed

WCF with WSHttpBinding on NetScalar - Security negotiation Issue.


Hi Gurus,


We have a WCF Service with *wsHttpBinding* and consumed by our windows application. This application consumes other services (asmx) too.


In Production we deployed this WCF Service on 3 machines. Service is working perfectly when under software NLB for load balancing.


Recently, our production environment has changed the Load balancing technique with *Citrix NetScalar* for VMs.

SOAP Security negotiation with "http://.." failed


I have WCF end-point service hosted by Windows Service and configured as:

A Sordid Little Tale Of Unexpected Security Exceptions

It was a dark and stormy coding session; the rain fell in torrents as my eyes were locked to two LCD screens in a furious display of coding . .sorry sorry, I just can't continue. It's all a lie. This actually a cautionary tale describing one subtle way that you can run afoul Code Access Security (CAS) when attempting to run an application in partial trust. But who wants to read about that? Right? Right? Well this isn't a sordid tale, but if you bear with me, you may just find it interesting. Either that, or you may just take pity on me that I find this type of thing interesting. I was hacking on NuGet the other day and all I wanted to do was write some code that accessed the version number of the current assembly. This is something we do in...(read more)

Round off time to the nearest minute

How would you round this up to the nearest minute? There isn't a built in function to do this so you have to use a little bit of maths to get there. There are 60 seconds in a minute. We already have 38 seconds on the clock. So we need to add on 60 - 38 = 22 more seconds.

SharePoint Tutorial - Security

Security in SharePoint is comprised of users, groups and roles.

Users, Groups and Roles

A user account comes from the authentication system. For example, if Active Directory is used to authenticate then the user accounts will come from it.

There are two types of groups SharePoint uses: domain groups and SharePoint groups.

How to get more information about the exceptions that can happen in SharePoint 2010 projects?

In case there is an exception anywhere in the SharePoint 2010 project (most common place an exception would happen is during deployment of your SharePoint project, custom deployment configuration or custom deployment steps), there's a registry key EnableDiagnostics available for you to use.

Performance Tests: Precise Run Time Measurements with System.Diagnostics.Stopwatch

Everybody who does performance optimization stumbles sooner or later over the Stopwatch class in the System.Diagnostics namespace. And everybody has noticed that the measurements of the same function on the same computer can differ 25% -30% in run time. This article shows how single threaded test programs must be designed to get an accuracy of 0.1% - 0.2% out of the Stopwatch class. With this accuracy, algorithms can be tested and compared.

Data Types - Date and Time in SqlServer

Date and time values can be stored with either the DATETIME or SMALLDATETIME data type. The difference between the two is that SMALLDATETIME supports a smaller range of dates and does not give the same level of precision when accounting for time. The DATETIME data type can hold values from January 1st of 1753 to December 31st of 9999. The time is stored to the 1 three hundredths of a second and each value takes up 8 bytes of storage. The SMALLDATETIME data type can hold values between January 1st 1900 and June 6th of 2079. The time is tracked to the minute and each value takes up 4 bytes of storage. The majority of business applications can live happily with SMALLDATETIME, however, if you are in an environment where each second matters or you need to make estimates to the distant future (or past) then you have to resort to DATETIME. If you fail to specify the time when inserting a value into a DATETIME or SMALLDATETIME column, a default of midnight is used. If you fail to specify the date portion the default of January 1, 1900 is used.

How to programmatically add controls to Windows forms at run time by using Visual C#

Add private instance variables to the Form1 class to work with common Windows controls. The Form1 class starts as follows:

.NET 4 Web Application Startup Time

I was chatting with Jonathan Hawkins and some of the folks on the ASP.NET team about performance and Jonathan mentioned the startup time for large ASP.NET applications is improved on .NET 4. There are some improvements in the CLR and in ASP.NET itself that helped. If you have a giant app, you should do some tests.
