  Configuring IIS 6.0 Machine.config for use in Web Farm (ASP.net 2.0) Reply Contact  So, where would I add the following line? (.net 2.0)  <machineKey     validationKey='A130E240DF1C49E2764EF8A86CEDCBB11274E5298A130CA08B90EED016C0 14CEAE1D86344C29E67E99DF83347E43820050A2B9C9FC89E0574BF3394B6D0401A9' decryptionKey='2CC37FFA8D14925B9CBCC0E3B1506F35066FEF33FEB4ADC8' validation='SHA1'/>   I have reviewed the following MSDN articles:   http://msdn.microsoft.com/en-us/library/w8h3skw9(VS.71).aspx   http://msdn.microsoft.com/en-us/library/ms998288.aspx   However, my machine.config file for ASP.net 2.0 does not seem to correspond with the article. Searching for "validationkey" in the  machine.config, machine.config.comments, and machine.config.default returns nothing.   I have entered the above validation key (different one of course) right below the <system.web> entry in the machine.config and reset IIS.   The users are still experiencing the same problem as before which is:   Message: 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.

  Re: Configuring IIS 6.0 Machine.config for use in Web Farm (ASP.net 2.0) Reply Contact You're on the right track.  Make sure the machineKey property is not also set in the application web.config.    Here is a search on google to create the machineKey you'd use. http://www.google.com/search?hl=en&q=machinekey+generator&aq=0&oq=machinekey+gen&aqi=g2g%3As1 Steve Schofield Windows Server MVP - IIS http://weblogs.asp.net/steveschofield http://www.IISLogs.com Log archival solution Install, Configure, Forget
