I have a machinekey set in web.config file, yet I still regularly receive:

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.

My host (Applied Innovations) suggested I change my sessionstate mode param to "StateServer" from "InProc".

Will this change truly work? Secondly, what are impacts to performance of site if changed?

Thanks in advance for any assistance.
