Speech Server 2004 R2 - Hangs loading page RRS feed

  • Question


    We have a Microsoft Speech Server (Version: 1.1.50414.1) application that has been running on IIS 6.0 without issue for 6 months. Two months ago we deployed several Microsoft patches to the system and now seem to be experienceing an issue where the IIS server is randomly unable to make pages available to the SALT interpreter. Unfortunately it is too late to revert back to a backup of the machine as we had it configured prior to the patches so could you please let us know if/what configuration changes to IIS or MSS were present in the patches we recently deployed ?
    This is the error that we are receiving.
