How can I block their Internet accesses other than receiving email and one specified application?
All clients on LAN are connected to the NET through a Leased line, our management don't like their staff surf the Net in or out of working hours. But they have to communicate by email.
How to do this?

Well, one thing you could do is to diasable any applications that browse the internet (ie. internet explorer). How you would do this is in the registry. Run regedit.exe and go to this key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Make a new DWORD value called "RestrictRun" with a value of 1 (enabled, dont allow applications) or 0 (disable, allow applications)

Then, under:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\RestrictRun

Make string s for each of the programs you want to disable, for example:

1 REG_SZ "iexplore.exe"
2 REG_SZ "netscape.exe"
3 REG_SZ "notepad.exe"
4 REG_SZ "wordpad.exe"

etc.

Answer 1 has given good info that pertains to the restriction,the registry changes will have to be applied to each machine individually and will also leave a backdoor open that will allow users to allow the user to access the internet,because the desk top settings are still the same.Reference other questions and answers in previous tech republic answers.
This can be done by typing typing internet or registry restrictions in the search in upper right corner.

Well, I have a temp solution, depending on the savy of the users. I would simply goto c:\programfiles\internetexplorer and cut the exe file to another place preferably off the local system for later recovery. Then when they click on the links for internet explorer it will not let them access the internet. They will get the cannot find program associated with the shortcut. Viola no more net access.

The process is simple but hard on employee relations. Don't restrict , rather log all activity that relates to the internet , there are some very good logging programs out there that will even log key strokes if you want, some somple searching like on ZD Net will reveal the programs , but require a Pass word to get access to the machines, this identifies the user , but don't let anyone know you are logging , or that you use a logger, then you can see who your security leak is and deal with it, in business , a back door opens every time an employee misuses the equipment, the other side of the coin is even seasoned users know they can't hide from a good logger as they have to identify themselves to log on.
