306|error|500|Validation of viewstate MAC failed

Hi All,
Could you please help me on the below error I am getting while replaying my script:
306|error|500|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.

Please suggest ways to mitigate this issue. I have correlated the viewstate, what additional steps needs to be taken to solve this issue.


Its a bit urgent. Please reply fast. Appreciate your help.

Warm Regards,
Koushik
