We were getting decryption errors on some servers after installing the ASP.NET security patches. The problems would occur when moving between two different .NET 2.0 applications on the same server. The forms authentication was not able to be decrypted
and it would throw an exception. The servers were not part of a load balanced server farm.
Despite it not being part of a server farm, the error seemed like the Framework was generating a different machinekey for each appdomain (the apps were part of the same app pool). We created a machinekey, placed it in the machine.config file and the decryption
errors went away.
