  • This seems to be a server configuration issue. The following link describes the solution of an issue similar to yours.

  • Not sure whether you resolved this or not but I had a simialr issues...

    This was due to a POORLY configed proxy server and pass-thru authenticate combined with the user selecting "Save password" when signing onto SSRS.

    To work round the issues access the Report Builder "click-once" app directly http://SERVERNAME/reportserver/reportbuilder/reportbuilder.application

    the full solution (if poss) is to clear down ALL IE data (inc password).
