I thought I had it all together with my security system which checks for Hard Disk Serial Numbers and hashes with company name to give a security code.

Along comes citrix with its ability to run the application from one machine by several users

Has anyone any comments on how I could secure the application to a set number of users

How does SQL Server handle the number of CALS ?

How can SQLServer Express2005 (or 2008) tell me how many people are logged on) ?

Thanks
