I am working with the ASP.NET Starter Portal and I don't think it is
related.
Everyone once and a while, after a rebuild, I get the following error. I am
not doing anything with Cryptography, but the portal framework might be, but
I don't exatcly what it is trying to do.
Sometimes refreshing works and sometimes I have to rebuild and other times I
have to do an IISRESET.
Any ideas?
Thanks!

Found solution at
http://www.derkeiler.com/Newsgroups...t.framework.aspnet.security/2003-05/0146.html

In the specific case of the ASP.NET Starter Portal this worked for me:
<configuration>
[...]
<system.web>
[...]
<machineKey validationKey="AutoGenerate"
decryptionKey="AutoGenerate"
validation="MD5"/>

Hope this helps you.
