The serialisation problem occurs when an ASP.Net page's viewstate cannot be unencrytped on postback. ASP.Net encrypts information such as form values and places it in a hidden field in the client HTML. This is encrypted using the information in "machine.config". This usually occurs if your application is using load balancing (IE: you have more than one server), the form has been tampered with or a postback sends incomplete data or your machine.config changes (I believe this can happen if .Net is reinstalled).

If you are on a server farm / using load balancing, take a look at this link for details of how to set all your machines to use the same encryption key;



would this be related to the error I posted in the initial question?  I only ask, because that error is causing IIS to crash, and thus 30-40 sites are losing service....
Your original error is a different matter. Have you tried the steps detailed here: http://support.microsoft.com/?id=885654 ?

If you have 30 - 40 sites - have you set them all up on different application pools? This should help keep the other sites running when the culprit site has caused it's pool to crash.
(Ignore my link - I didn't spot it was the same as the others!)


honestly.  I'm not in charge of the servers, my boss is and he is not very quick when it comes to stuff like this.

I will mention to him about the different application pools.  I know right now, there are not seperate.
Once they're seperate - then only the site(s) causing the problem will crash. That's step one on your way to solving the problem!


I agree.  I passed on the information, I should here from boss man in a couple hours about this.  (he's on West Coast US, I'm on East Coast)  :)


ok.  He has come back with a worry about the amount of RAM this would take up with the sheer number of sites on each server.

Is there a way to throttle the memory?  I see that the CPU load can be throttled....?
In the app pool properties, there should be a recycling section where you can limit the size of memory used. When talking about server ram (I'm assuming you have > 1GB) then the extra overhead of new application pools is really small.
