We have an SBS 2003 Server with 4 users connecting to it. Around 5:30PM every day, the users lose connection to the server. When they try to reconnect to the server, they are asked for their username and password, but that doesn't seem to work. They have to reboot their systems to reconnect. Now, the users have told me that if they logon, say later in the day (i.e. show up around 12PM and logon), that they have no problems. Or, if they reboot say, around 3:00PM, they work fine for the rest of the day. If they logon, around 7:30AM, and after about 10 hours (5:30PM), the server "kicks them out". I have checked the user profiles and logon times - all users can logon at all times of the day. And I have checked that there are no policies stating they have to logoff after xx hours. Could you please help me resolve this "wierd" issue?
