From: G Zhao on 3 Sep 2009 03:18 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. "Alexey Smirnov" <alexey.smirnov(a)gmail.com> ???? news:00e85d13-6fe5-4e60-b2d9-434d8932ec55(a)r9g2000yqa.googlegroups.com...
