Terminal Server per device CAL behavior

Posted on 2010-01-08

Our site accesses multiple terminal servers (kind of the reverse of multiple users accessing a single terminal server.)  The TS licensing at each server is configured with per-device CAL's.  

What I'm seeing is once a client computer here accesses a TS server, if it hasn't been assigned a device CAL it will pick one up from that server.  If it already has one (even from a different server) then nothing happens with that TS server's licensing.  Ie, the device CAL is assigned to the client computer and is then valid for any terminal server until it expires.  Is this correct?

If I'm understanding this correctly, is there a way to purchase a TS device CAL and directly assign it to a local workstation (and doesn't expire) rather than picking them up randomly from various TS license servers?

    Yes, this is normal behavior. The TS will forward/proxy the client request to the TSLS it's aware of and acquire a TS-CAL. The device TS-CAL is stored locally on the client and will be renewed when it expires.
    It's as I know not possibly to get a TS-CAL that isn't timebombed.

    I understand it as you have TS Licensing Server installed on each TS. Not necessary to have TSLS installed on the TS. You can consolidate the TSLS and make all TS use the same pool of CALs. To consolidate the TSLS, you nead to have the TS-CAL license key available to register it on the centralized TSLS.

    Configure each TS to use the centralized TSLS as its  preferred TSLS

    Thank you.  I will review the document link.  An aspect I forgot to mention is the various TS sites are not associated in any way and have their own users that RDP in so their CAL's can't be combined into a centralized TSLS.  Can I configure the local clients to look at a local TSLS for their various RDP sessions rather than the remote TSLS?

    No, the clients only contact TS, and TS contacts TSLS.
