Web Farm Error

Hi All

I am trying to install the free edition but when i get to the key validate section on the installer i get this error.

##################################
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.
##################################

The host i am with is www.serverintellect.com and i am unsure what steps to do or what i should be editing?

Any help on this would help.

Thanks
Andy

RE:Web Farm Error

Hi Andy,

You should put machineKey setting in your web.config. Here is an example:

<machineKey
validationKey="AutoGenerate,IsolateApps"
decryptionKey="AutoGenerate,IsolateApps"
validation="SHA1"
/>

But you will need to insert your own keys instead of 'AutoGenerate' setting. Or you can disable viewstate MAC validation by setting enableViewStateMac property of <page> element to false. You can find more information at:
