Silverlight errors

[Migration User]

Ok, I HAD everything working, and suddenly Silverlight is failing on me on several (but not all) pages.  Basically I can't get to any of the "Manage" pages at all.  I keep getting the following error:

 

Webpage error details

The URL listed in the error takes me to a page that shows the following:

 

Exception Message Details

Value	Initialization failed.
Resource ID	IsolatedStorage_Init
DLL	mscorlib.dll
Version	4.1.10111.0

This webpage provides developers with Silverlight exception message text, which can be useful in diagnosing failures and problems with Silverlight applications. Some exception strings contain tokens for additional information produced by your application.

To see these descriptive error messages on your local machine and obtain other debugging resources, please install the latest version of Silverlight for Developers on your Windows or Mac computer.

So that's not very helpful, other than to tell me the page isn't working.

I've tried rebooting the server and restarting IIS, but nothing has worked.

Help?

Interestingly,  this error appears only on the client.  There are no errors logged in the Altiris logs at all.  Also, I can open the web console on the NS and it works perfectly.

So I'm guessing this is a browser or local Silverlight issue.  I'm going to uninstall and reinstall Silverlight on my PC and see if it fixes it.

(Seriously, the person who decided Silverlight would be the Web console platform should be FLOGGED for stupidity.  We need an HTML5 version!)

Find the Silverlight plug-in UI on the client (just search Programs) and double click it.  Go to the last tab (Application Storage, I believe it's called).  Highlight any entries that match your NS server same and select Delete.  Don't worry, it won't hurt anything...but should fix your error.

Didn't work.

There were no entries for the NS, only one for Technet.  But I cleared everything anyway.  Closed and reopened the browser (IE8) and same exact error.

Ok, Fixed it.

 

On the Silverlight console on the Application Storage tab, there is an "Enable application storage" checkbox.  This was UNchecked.  (Must be the new default setting as I hadn't touched this ever before.)  Checking this box immediately returned function to the NS console.

I still say using Silverlight was a bad idea though.  Should be HTML5 or something more cross-platform than Silverlight is.
