SharePoint 2010 Secure Store Proxy Unexpected Exception
This alert condition indicates that a Secure Store proxy unexpected exception occurred. Possible causes: the application server may be down or inaccessible due to network issues, or the secure store service application may not be provisioned correctly. If the secure store service application is enabled on more than one SharePoint server, client computers will not be affected. Otherwise, computers relying on the secure store credential database will fail to authenticate and will be unable to access the SharePoint site.
