It can occur because of Microsoft® Windows DEP (Data Execution Prevention) on the server. DEP simply kills the lmgrd application when it starts.

The suggested solution is:

1. Stop the license service using LMTOOLS.EXE or the Windows Services dialog box.

2. Open Task Manager and stop all processes named like lmgrd.exe and cameo.exe

3. Select Control Panel > System > Advanced > Performance Settings > Data Execution Prevention

4. Select the Turn on DEP for all programs and services except those I select check box and add to the list LMGRD.EXE, LMUTIL.EXE, LMTOOLS.EXE, and the vendor daemon, where the license manager is installed

5. Restart the service

DEP also may impact LMTOOLS.EXE crashes or stops the license service (you cannot checkout any licenses then). It is known that such a situation occurs not only on the Microsoft® Windows 2008 server but also on the Microsoft® Windows 2003 server.
