We need suggestions for reconciling network security with the requirements of the lab software and for preventing crashes. The 21 PC's are connected to a local proprietary network for the server running Tandberg's ICM software and ClassNet. The entire lab is also connected to a second network for log on, Internet access and drive mappings to file servers on the campus network. The campus network connection also affords access to a server running Rosetta Stone. For security reasons, all lab users including teachers working at the server machines must log in and out using their campus domain usernames and passwords. This creates a communication problem between the student stations and the teacher machine, which is the ICM server. When a teacher or student user logs out, the ICM and/or Divace software is automatically closed. When it is subsequently reopened by later users, the ICM server can no longer reach out to the student stations. For example, it is not possible to launch Divace Duo or to shut down the student machines from the ICM. When Divace Duo is open, error messages sometimes appear on the student machines warning of communication problems with the ICM, and student work is sometimes lost. Has anyone found a solution to this problem? Secondly, our lab and its Tangent computers are four years old and have unfortunately been plagued since opening with technical problems which severely limit its use. The most common problem is machines freezing and crashing. Up to one third of the lab crashes each day, a problem which persists even though the student stations were just reimaged. The crashes occur about equally on start up, on shut down and while running during the day. Our IT department believes that the problem is somehow caused by the nature of the proprietary network installed by Tandberg, or by its interaction with the campus network. Has someone experienced problems of very frequent crashes who could suggest some steps to troubleshoot? Thank you. Julia Tebbets French Teacher Sewickley Academy
