SharePoint Annoyance of the day – Cryptography nightly error on a server

Dear all,

If you encounter like we did on one of our testing server  a popup (appearing in the morning) with a cryptography exception and wanting to attach the VS Debugger Process, don’t worry. It’s documented and somehow normal.



This will only happens on some configurations  and if we have VS installed on the server (it’s usually not the case on staging environment and definitively not on authoring / production environment) otherwise a warning will be logged and nothing else.

In case you encountered the same behaviour of the customer would be complaining that any of your solution is doing something harmful (after all, a cryptography exception is quite frightening by its sole name), please refer him to this entry
