License Manager Error -3: License Checkout Failed. Cannot
Connect to a License Server
This error can indicate that the SERVER or DAEMON lines in your License File is
incorrect or missing. To remedy this error, try the following:
Note If you make any changes to the License File on the license server, you
must restart the license manager.
Make sure that the SERVER Une in your License File matches the SERVER line
in the License File on your license server. On client systems, the License
File is matlabroot\R2006b\bin\win32\license.dat; on your license
server, the License File is matJabroot\R2006b\f lexlm\license. dat, where
matlabroot is the root MATLAB installation folder.

Make sure that your License File includes a DAEMON line. See "DAEMON
Line" on page 3-7 for more information.
Make sure the TCP port number used by the license manager is not already
being used by another application. This port number appears at the end of
the SERVER line in your License File, as in the following.
SERVER hostname INTERNET=128.36.2.12 27000
To determine if another application is using this port number, use the
netstat command. On Windows 2000 and Windows XP systems, run
C:\WINNT\system32\netstat -p tcp
If you find the port number used by the license manager in the information
retumed by netstat, the port is in use. Change the port number on the
SERVER line in your License File to a port that is not already in use. By
default, FLEXnet uses a port number in the range 27000 to 27009.
Make sure that you do not have multiple MathWorks vendor
daemons (mlm.exe) running. Check your FLEXnet log file
(matiabroot\R2006b\flexlm\lmlog.txt) for the error Multiple MLM
Servers Running.
