Hi,
I am getting this when I run it on asp.net 2.0 but works find on asp.net 1.1

. 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.

Please help. Thanks.
 
Check into the EventValidation mechanism of ASP.NET 2.0 and how to disable it.
Let us know if that fixes your issue. Is anything (form elements, items)
added to the page dynamically that would cause event validation to fail?
Is this one machine, or a farm? You didn't specify.
Peter
