The License Server is a key component of the NetCool infrastructure that manages the number of users/clients that are allowed to communicate with the server components of NetCool. This is a big change from traditional Tivoli that do not do any license enforcement.
The problem with the License Server is on Windows 2003. Windows 2003 has Data Execution Prevention turned on by default and gets in the way of the "lmtools" application along with a couple other programs..
Everytime I added an exception to the list, I got another pop-up saying that Data Execution Prevetion prevented another NetCool application from running. So I figured out how to turn off Data Execution Prevention completely.
You must first change the attributes of the boot.ini file so it is not Read Only. Then edit the boot.ini file and make it look kind of like this one...
multi(0)disk(0)rdisk(0)partition(1)WINDOWS="Microsoft Windows 2003 Server" /FASTDETECT /NOEXECUTE=ALWAYSOFF
Adding the /NOEXECUTE=ALWAYSOFF will disable data execution prevention system wide.
This has proven to be very handy...
