Error message from the provider: The RSA key container could not be opened.

[peter.freeborn]

I am using RTM on Windows 2003

I have been trying to encrypt the connection string in the Web config
with the following command line on the web server

C:\WINNT\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis -pe
connectionStrings

-app / -site dev-emts

The Application is in the root hence the "/"

The site is called dev-emts

It works for a while.


But for no reason I can see it seems some cached value or somthing is
expiring then no one can get in and it throws the following error...

Parser Error Message: Failed to decrypt using provider
'RsaProtectedConfigurationProvider'. Error message from the provider:
The RSA key container could not be opened.
