How to limit access to a group for particular teachers.

By default all new groups have full access rights for all teachers, i.e. any teacher may enter the group. To limit access privileges for any group:

- open the Connection Server Management Console (on Server computer click Start -> All Programs -> Net Control 2 -> Connection Server Configuration);

- on Groups tab select a group and click Access permissions button on top toolbar:

In the appeared dialog:

delete <All users> group from the list. Click Add button and add teacher accounts or teacher groups, which should have access to the group. Click OK.
