MDS 2012 error when creating Model RRS feed

  • Question

  • Installed 2012 MDS on my laptop (Server 2008R2)
    Installed successfully and I was able to create the MDS database and website.  I can browse to the Master Data Manager tool and go to System Administration - attempting to create a new model fails with:

    [HttpException (0x80004005): Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. expand »AutoGenerate cannot be used in a cluster.]
        System.Web.UI.ViewStateException.ThrowMacValidationError(Exception inner, String persistedState) +11364542
        System.Web.UI.ObjectStateFormatter.Deserialize(String inputString) +11364977

    All googling has led to some issues with a .Net SP and no real solutions

  • Guess I should have tried a few more things before posting.

    Accessing the master Data manager via localhost instead of the machine name seems to have solved my problem.
