Validation of Viewstate failed RRS feed

  • User565442435 posted

    I have my application set up that any time there is an error, I get an email. I just got the genereic valdation of viewstate failed.

    Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. See http://go.microsoft.com/fwlink/?LinkID=314055 for more information.

    I was under the impression that if you have a machine key specified in the web.config, this shouldn't happen? I do have a machine key defined, any ideas what would cause this?
