I have coresight 2013 installed and it was working perfectly although the kerberos logins are not working as expected, i.e. I have to enter an explicit domain user/password.
I tried today and I see that silverlight add-in will not load when the coresight application is opened. I checked mime-types and filtering and they all look OK.
There are no messages anywhere to indicate why silverlight is not loading.
What could be the issue and how do I go about debugging this?

Lubos,
I only have the option to use IE 8 on the web-server machine.
I dont have a client machine that I can use. coresight/admin page works fine but that does not use silverlight.
I will add the coresight page to the local intranet page to see if it will log me in automatically with kerberos.
When I open the coresight page it shows an image saying that silverlight needs to be installed. I am then prompted to download and install silverlight from the internet. I do this, but afterwards the page is blank with the frame for where silverlight should be with a red X on it to indicate that it has not loaded.
The site used to work from the local machine fine so I am not sure what has caused the change.
Simon, have you checked the Application Event log?
In IE, go to Tools > Manage Add-ons > Toolbars and Extensions > Under Show: click All add-ons > click Microsoft Silverlight. Is it enabled?
Were you logged in as local admin when you were installing Silverlight?
Lubos,
Sorry for late reply. I had some hardware issues with my laptop.
I have gone onto the IIS Server and I see that Silverlight 5.1.30214.0 is enabled but not loaded.
I spoke with IT and they think that there is a policy in place that prevents a browser session on a server console browsing to a locally hosted site. But I am sure that I have done this before. I have requested a client based IE session to test remote connection.
One other thing that changed since I last looked at this system was that this Coresight installation is on a Test Server and the default bindings of the site are changed so that the host name has been set to coresight-test and coresight-test on port 8080.FQDN. DNS entries for these names have been set. So rather than addressing coresight using http:\\<machinename>:8080\coresight you use http:\\coresight-test\coresight.
I should that I was able to previously use localhost as the machine name to connect to the coresight application and maybe that was how I was able to open the browser.
Since the new bindings were added I guess that this somehow prevented me from using this method.
Hi Simon,
What web browser are you using? I would try at least two different web browsers.
If you're using IE, make sure that the Coresight page is in a zone that allows running Silverlight plugin. In addition, if you're working on Kerberos (and assuming SPNs and delegation are correctly configured), you should add the Coresight page to Local Intranet zone in IE to be logged in automatically using your Windows credentials.
Does Coresight page load ok on a different machine?
Do you get any error at all or just a blank screen?
Is there something related to Silverlight in the Application Event Log?
If there are no clues, I would uninstall Silverlight and reload the page - it should prompt you to download and install Silverlight again. Do that and refresh to see if that helps.
