One thing that quite frequently happened to me: I worked with MS SQL Server Reporting Services for quite a while, due to some reason (that I cannot assign right now) while accessing the ReportManager I get the following error message “Failed to decrypt symmetric key”. The suggestion now is to run RsKeyMgmt to delete all encrypted content and to run RsConfig to re-generate a new key. However, when running RsKeyMgmt on my machine running a German version of Windows XP I get the following: After I type in J and click on ENTER nothing happens.
