Multiple Data Source Connections into a Loop

[egates17]

When connecting to a datasource our users typically are presented with a prompt allowing them to select from one of multiple connections.  This appears to have been impacted by Microsoft Updates from this past weekend.  Now when a users selects the prompt the prompt value does not resolve,  instead it goes into a loop returning to a prompt with blank radio buttons.  Has anyone else experienced this?  Cognos 8.4.1

I've seen similar.  What happens when you test each of the connections in Cognos Administration? Also, are you using single signon?
