I have several users who cannot save a default printer in terminal server. Everytime they log off and back on it sets the very first printer as their default, no matter what the default is on their local machine and no matter what they set as the default the last time they logged in to terminal server.
I have on user who has had this problem the whole 2 months this terminal server has been operation, and other users who were able to set their default printer until last night. This morning they logged in and were not able to save their default printer. No changes were made overnight.
