How can I get a list of users using a specific toolbox?

I am running Matlab R2014a with network license. Matlab gave me following error when I run

normrnd(0,1)

Error:

License checkout failed.
License Manager Error -4
Maximum number of users for Statistics_Toolbox reached.
Try again later.
To see a list of current users use the lmstat utility or contact your License Administrator.

Troubleshoot this issue by visiting:
http://www.mathworks.com/support/lme/R2014a/4

Diagnostic Information:
Feature: Statistics_Toolbox
License path: C:\Users\UsrName\AppData\Roaming\MathWorks\MATLAB\R2014a_licenses;C:\Program
Files\MATLAB\R2014a\licenses\license.dat;C:\Program Files\MATLAB\R2014a\licenses\network.lic
Licensing error: -4,132.

I tried 'LMTOOLS'> 'Server Status'> 'Perform Status Enquiry'. It outputs the following.

The license files (or license server system network addresses) attempted are 
listed below.  Use LM_LICENSE_FILE to use a different license file, or contact your software provider for a license file.

For further information, refer to the FlexNet Licensing documentation,

available at "www.flexerasoftware.com".

Is there any way to know how many License are available for a specific toolbox and a list of users whose who are using it?

I know this article.

Is your use case an end user perspective? Like you want to contact someone to free the key?

Or is it you are an admin and want to count etc?

[Pankaj]

I am not an admin, am a user. I want to run my code which needs Statistical Toolbox, the option of contacting someone and request to free the key is there. I am receiveing this error since long, was curious whether the user limit has actully reached or there is some other problem.

[Andreas Goser]

The admin has log files and sometimes reports and can collaborate with MathWorks to identify the best number of keys or if a different license type makes sense.
