System.Security.Cryptography.CryptographicExceptio n (incorrect parameter)

[jasonjbwalton]

Hi

I am implementing a solution based upon Sitecore CMS version 4.3.2.6
..Net 1.1 on a Windows 2003 server

We are experiencing an error once in a while when transforming XML with
XSLT. We receive an exception

System.Security.Cryptography.CryptographicExceptio n (incorrect
parameter)

This exception only appears every now and again but the only way we can
find to get past the error is to restart the sites application pool via
IIS Manager.

Has anyone an idea why this exception might arise. We are not using any
encryption and the problem does not arise in our development or test
environment (these environments run Win XP)

We have noticed something a little strange. We can remove the error in
one of two ways.

1. Recycle the application pool - if we set IIS up to recycle the
worker process alone the error does not disappear.

2. If we add a user e.g. "Everyone" to the websites web folder and give
it full access to the root folder and all sub folders and files the
error disppears for at short while. Then it turns up again after a
short while - all the rights are still applied on the
folder/subfolders. One the error has appeared we can remove the
accounts rights from the root folder and all subfolders/files and the
site runs again ... for a while etc etc etc

We have several sites running on Windows 2003 Standard Edition and have
never experienced the error before, however, the Windows 2003
installation has the Danish User Interface Pack Installed.

Has anyone experienced any problems when using language pack on Windows
2003 servers ?
