Internet Blocking Tool (InetBlocker) application has been developed for an easy ISA/TMG server control by inexperienced users (common teachers, not network administrators). It allows blocking or unblocking internet connection for defined groups of computers without direct work with ISA/TMG server in an easy and quick way. Authorized persons (teachers) can control classroom internet connection in a simple application environment.

More details about this tool (in English) can be found in the following document:
If you want to learn more about ISA Server, there is also a very good guide for school administrators:


Aplikace Internet Blocking Tool (InetBlocker) byla vyvinuta pro snadné ovládání ISA/TMG serveru nezkušenými uživateli (běžnými učiteli, ne správci sítě). Umožňuje rychle zablokovat nebo odblokovat připojení k internetu pro definované skupiny počítačů bez přímé práce s ISA/TMG serverem. Pověřené osoby (učitelé) pak mohou z prostředí jednoduché aplikace ovládat připojení učebny k internetu.
