ViewState does not keep variables and errors out.

Question

Let me see if I can re-word this better and maybe get some more relavent answers or ideas. This has happened a few times now as reported by users. I cannot reproduce on my local server. I am checking each of the IIS settings now to make sure they match.

But on our production server here are the details:

Single Server

No Authentication

IIS7

ASP.Net 3.5

Totally Random when it happens

Using ViewState

Any Ideas? The actual error from the event log!

If the authentication ticket expires you could have that error.
