What kind of checks can I perform to be sure it is the firewall and not something else? Which specific ports should I check in which way to get conclusive evidence?

  • Credentials Not Passed From SharePoint WebPart to WCF Service

    - by Jacob L. Adams
    I have spent several hours trying to resolve this problem, so I wanted to share my findings in case someone else might have the same problem. I had a web part which was calling out to a WCF service on another server to get some data. The code I had was essentially using System.ServiceModel; using System.ServiceModel.Channels; ... var binding = new CustomBinding( new HttpTransportBindingElement { AuthenticationScheme = System.Net.AuthenticationSchemes.Negotiate } ); var endpoint = new EndpointAddress(new Uri("http://someotherserver/someotherservice.svc")); var someOtherService = new SomeOtherServiceClient(binding, endpoint); string result = someOtherService.SomeServiceMethod(); This code would run fine on my local instance of SharePoint 2010 (Windows 7 64-bit). However, when I would deploy it to the testing environment, I would get a yellow screen of death  with the following message: The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate,NTLM'. I then went through the usual checklist of Windows Authentication problems: Check WCF bindings to make sure authentication is set correctly Check IIS to make sure Windows Authentication is enabled and anonymous authentication was disabled. Check to make sure the SharePoint server trusted the server hosting the WCF service Verify that the account that the IIS application pool is running under has access to the other server I then spend lot of time digging into really obscure IIS, machine.config, and trust settings (as well of lots of time on Google and StackOverflow). Eventually I stumbled upon a blog post by Todd Bleeker describing how to run code under the application pool identity. Wait, what? The code is not already running under application pool identity? Another quick Google search led me to an MSDN page that imply that SharePoint indeed does not run under the app pool credentials by default. Instead SPSecurity.RunWithElevatedPrivileges is needed to run code under the app pool identity. Therefore, changing my code to the following worked seamlessly using System.ServiceModel; using System.ServiceModel.Channels; using Microsoft.SharePoint; ... var binding = new CustomBinding( new HttpTransportBindingElement { AuthenticationScheme = System.Net.AuthenticationSchemes.Negotiate } ); var endpoint = new EndpointAddress(new Uri("http://someotherserver/someotherservice.svc")); var someOtherService = new SomeOtherServiceClient(binding, endpoint); string result; SPSecurity.RunWithElevatedPrivileges(()=> { result = someOtherService.SomeServiceMethod(); });

  • What does it take to successfully run a URL shortener service [on hold]

    - by MxyL
    What are the costs (technology wise) for running a URL shortener service such as bit.ly or anonym.to? For example, if I decided to use an inexpensive shared hosting with "unlimited" bandwidth, would that be feasible? Or would I need a dedicated hosting? I found this question: I want to run a URL shortener for my own usage, what do I need to do?, which makes it easy to set it up, but I'm not too clear what kind of things I need to consider.

  • Database Administration as a Service

    A DBA should provide two things, a service and leadership. For Grant Fritchey, it was whilst serving a role in the Scouts of America that he had his epiphany. Creative chaos and energy, if tactfully harnessed and directed, led to effective ways to perform team-based tasks. Then he wondered why these skills couldn't be applied to the workplace. Are we DBAs doing it wrong in the way we interact with our co-workers?

  • Good Customer Service Example

    - by MightyZot
    Here’s another good customer service example for you! My wife purchased a Galaxy last week and she loves the phone.  She asked me to add it to our AT&T Microcell last night. I purchased the AT&T Microcell a couple of years ago, because cell signal out where I live sucks! Since microcells are managed on the AT&T web site, I went to the site and tried to sign in. Naturally, having not managed that microcell in a couple of years…and much to my chagrin…I discovered that I didn’t know my password OR my user ID. So, I decided to call and see if I could get my account reset that late in the day (we’re talking last night, so it was well after 7pm.) I called the technical support line, touched the appropriate numbers to navigate to microcell support, turned on my speaker phone, and prepared for the long wait. After about 45 seconds I was delighted to hear “Jeffrey” break in and ask what he could help me with. I explained that I have not managed my microcell for some time and had forgotten the user name and password.  “No problem”, he replied, and he asked me for the line I used to register the microcell. After confirming the last four digits of my IMEI number, he asked me for my wife’s number. I gave him my wife’s number and he said, “I’ve taken care of it Mr Pope. Just have her reboot her phone and you should see your microcell.” We rebooted her phone, it connected to the microcell, and voila, she was online! “Is there anything else I can help you with while I’ve got you on the line”, he said. “Nope”, I replied. “Ok, have a great night.” What made this a great customer service experience for me was that “Jeffrey” didn’t stop at giving me my user account and password, which I would probably forget anyway after setting up my wife’s new phone. Instead, he solved the real problem for me – adding my wife’s new phone to my microcell. Great job Jeffrey!

    I'm looking for information about service excellence topics such as: 0 downtime deployment how to deal with versioning (backward and forward compatibility) environment strategies (how many staging envs ? etc.) performance testing testing in production monitoring I am looking at the Microsoft stack, but the concepts should be the same everywhere. Do you have any recommendations of books or blogs on the subject? PS: I have found some good articles from I.M.Wright's "Hard Code" blog. Anything else?

  • Why an SEO Article Service Should Not Bite the Language That Bites Back

    As a professional SEO article service I have witnessed a great deal of confusion, misunderstanding and downright idiocy when it comes to writing articles for the web, or content for websites. Creating effective SEO articles or search engine optimized content is not easy - yet so many people seem quite happy to take people's money despite, for example, having only a passing appreciation of the English language!

  • mongodb with 13.10 service problems

    - by No_name
    I installed mongodb with the instructions here. Fresh installation of ubuntu btw. It installed without error, but upon attempting to start, stop or restart the service, I got start: Unknown job: mongodb Invoking "mongod" from the commandline seems to work, as I can view statistics of mongodb fine from localhost:28017. I've also attempted to use the official ubuntu package "mongodb" instead of "mongodb-10gen" but no luck there either.
