We have a client who has a 2008 Enterprise 32 bit terminal server. Randomly printer redirection will begin to fail for all users. I thought we had tied it into one particular system that may have corrupt printer drivers as I tied the first error the event log: "Unexpected internal error in TS RDP device redirection. Contact technical support." to the same time the user logged in one morning. However, today printer redirection is working after a reboot and that same user has logged in from the same system and it did not break printer redirection. Any ideas on how to track down what is causing this? It cropped up out of nowhere.
