I have created my application in webfarm and i cannot resolve this error.I have tried all sort of things to solve this error,but cant get through.

Error is:
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. AutoGenerate cannot be used in a cluster.
