Liberacion de licenciamiento manual en Citrix,

XenDesktop User/Device manually release a license

June 10, 2013 Leave a comment

Many companies are switching to XenDesktop User/Device licenses vs. the traditional concurrent model. The main reason… well they are are just about half the cost. So it make sense from a budget perspective.

This does create a bit of additional administrative IT overhead. In theory the license server “takes care of” managing licensing”, etc… however, Every now and then you’ll find that you might need to delete/release a few licenses on your XenDesktop installation, generally due to over usage, this will prevent a user getting “not enough licenses available” error.


Windows 7
Citrix XenDesktop 5.6
PVS 6.1.16
Citrix Receiver 13.4

Differences between the two: (Detailed info @ CTX135501)


A concurrent XenDesktop license is tied to a XenDesktop session, not to a specific user or device. When a user launches a session, a license is checked out to that session

User / Device:

XenDesktop User/Device licenses provide customers with the maximum flexibility of assigning a single license to either a user or a device and supports both license types in the same environment.


Head over to your license server

Run the following command from C:\Program Files (x86)\Citrix\Licensing\LS (default license location)

udadmin -list


This command displays who is currently using a license and when it is due to expire.

Find the user who you want to delete and then type the following command.

udadmin -f XDT_ENT_UD -user druiz -delete

Some other command examples

udadmin -list
Displays all the users and devices.

udadmin -list -a
Lists all features, versions, counts of licenses, and the users and devices for each feature.

udadmin -f XDT_ENT_UD -user druiz -delete
Releases one user from one feature.

udadmin -f XDT_ENT_UD -device druiz_xdwin7_64 -delete
