I am running SBS 2003. I am getting a MSExchangeTransport Event 999 (Routing failed to acquire the handle to the existing key container within default cryptographic service provider (CSP)) every 30 seconds. I have not been able to find much information regarding this event. Recently the server's system state was restored after a failed migration from the SBS 2003 to STD 2008 R2. The migration failed because of some incorrect permissions. Also, the server loses all of it's CALs every few hours, which then need to be restored or re-typed in.
