Error: Validation of viewstate MAC failed

[G Zhao]

Error:
[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.]

I got this error intermittently and an 'iisreset' command can solve it
temporarily.
Can anybody help me ?
I'm using IIS6 & Win2003.

This problem happened intermittently. And all clients got this error at the
same time. An 'iisreset' command can solve it.

So, I think your link can not fundamentally solve the problem.

But , Thank you for reply.
