Technical Solution


When you launch the Deployment Portal within the Notification Server console, you may see the upper-left 2 panes empty, though the lower left and right panes work fine, along with all other features.  If all panes are blank, this is a different issue logged here (KB 51549) and generally only seen when running the console remotely.  This issue can occur on the NS as well as remote consoles.  Additionally, 60 seconds after launching the portal (the default time-out for Silverlight), you'll get an error in the lower left corner of the Browser that reads something like this:

Message: Unhandled Error in Silverlight Application [Async_ExceptionOccurred]

This is a generic error saying something didn't work, though the details do give some indication on where the problem exists.

Additionally, you may see an error on your SQL server in the app event logs saying that access was denied for user Anonymous.


DS 7.1 Portal


This is caused by impersonation errors in the SilverLight console.
