Viewstate error

[Thiago Temple]

I have a site that is is a web farm with 2 servers using road robin load
balance...
Sometimes when I submit a form the following error shows up.
Does anyone know what to do?? I'm using the Framework 1.1

Thanks

Thiago

Are both servers using the same machineKey settings? If not, you need to
manually create the keys to avoid this error. If so, you may need to work on
either your ViewState or ViewStateMac settings.
