Hello, I have a problem with connecting to students. I've installed NSS in all computers in the classroom, but it doesn't show all students when I refresh the view.
Every time, 3 or 4 PC's are not shown, when students are normally logged in as simple users. When I turn on all PC's in the classroom, and when students are not logged in, the program works fine and I can see all PC's. After I refresh the view, they are gone. I have tried to reinstall NSS Student version on those PC's that are not shown, but it's still not working. I have also tried to log in students as an administrator, but it didn't help. On this picture, when I double-click on the student that is not shown, it says the #1704 error.
In configuration settings, I have putted that it's searching by IP range (IP is static in whole classroom) and Browse mode is U21 (Browse and connect students starting with : U21). Any ideas?
