Session Query !

Hi,

OUr client using Navision 3.70 with Navision Database Server. They are having 20 User Licence.

There are more then 20 user that can be logged on the Navision, But sometimes we need to delete the session forcefully. But as far as my knoledge is concern i can go to the session table and i can select the user name but when i say delete then at that time it says that The Session Table is Read Only.

But in the Books from Microsoft Development they have written that you can delete the session as and when needed.

So pls let me know how to delete the active session.
