Can you please describe in more detail what did you exactly do to solve 
the problem. 
What do you mean by problem with clusters ?? I am seeing the same problem 
as soon as we moved the code to production. And need to solve the problem 
immediately.

Thanks,
Meenu.

jus in case anyone else needs it.
Thanks

Hi'
This is one of the causes, not sure if you tried this :
 when in a web farm/ cluster,if the encrypt and decrypt key for "<system.
web>
-- machinekey" do not match the machine.config file, then you are bound
to see this or in other words, if they r set to auto then they won t matc
h
and would cause this.
So, find out the correct key  and instead of auto put this value in for
the encrypt and decrypt, for one of ur webservers, and copy the same key
into the other webservers as well.

follow this article for it

Q313091 HOW TO: Create Keys with VB .NET for Use in Forms Authentication
http://support.microsoft.com/default.aspx?scid=3Dkb;EN-US;Q313091
this shows you how to create the key for your webserver.

to find the place you need to change in your machine.config file
location of machine.config : \winnt\microsoft.net\framework\currentversio
n\config\machine.config\
open it and
then search for "<system.web>"
then search for "machinekey"

make sure the encrypt and decrypt keys are not set to auto. This is the
most common . If this doesn not fix it, this also happens to be a bug wit
h
microsoft .NET environment, so, you might wanna contact them or find a wa
y
to woork around it.
hope this helps

regards
  sairam.

Also besides making machine encryption/decryption key the same on all web
servers in the web-farm.  Also another item we turned off was
enableviewstatemac="False"  the 1.0 of the .NET framework has this turned on
by default.
