Hi Andrew
We use user CAL's. I will install this service on a DR WI Server - good idea..
Can I activate the DR TS License Server without installing any licenses? Im
assuming temp licenses will be used once its activated for users without a CAL?
Will also check to see if the server is in enterprise mode..
Thanks for all your help
Ang

First question, /user or /device cals? If its /device you’ll need to put some
licenses on there. Either way *activate* the secondary server. Don’t put stuff
off – in a DR situation you’ll be worrying about bigger things that ‘activate
the license server’ There shouldn’t be any need to change the GPO – you can
list multiple license servers – and license servers (in enterprise mode)
communicate with each other. Personally, I’m not a fan of sticking licensing
services on a TS box – is there not a WI server you can put that service on?
(I’m working on your WI service not being hosted on XenApp either – again, not
a fan if I can get away with it) In the event of a OhMy[insert deity of your
choice] scenario - *restore* your original server – don’t not do backups.

Thanks for your response. We do run Windows 2003 Servers. Would the following
work:
1) Install Terminal Services Licensing on an existing XenApp server in the DR
Site. Do not activate or install licenses
2) In a DR scenario, change the GPO that sets the TS licensing server so all DR
XenApp servers point to TS licensing server in DR site.
If my understanding is correct, existing clients with a valid CAL will work
anyway. New clients without a CAL will connect to the DR TS Licensing server
and be given a temporary CAL which will last 120 days. It simply allows me to
save some time in a DR so I dont have to call MS Clearinghouse. I simply need
clients without a CAL to be able to login. Would this work?
Thanks

user mode, really you just need activated license servers: although this isn’t
the case for /device. However, bear in mind that this is no longer the case in
W2k8R2 Remember that if a client presents a valid, unexpired CAL to a terminal
server upon connection, the server will allow the connection without contacting
a license server because the token has been validated by the terminal server
itself. You get need to get a license when: 1 - The client has never been
issued a CAL for the environment, neither temporary nor permanent 2 - The
client has been already issued a temporary CAL, and is in need of a permanent
CAL upgrade 3- The client has a permanent CAL that will expire within 7 days,
or the CAL has already expired, and needs to be renewed So in your DR, you’re
really considering the last 2. Temporary licenes could be issued by any TS
licensing server - so in DR you could have an empty authenticated server
allocating licenses - so then its only (3) that could be a problem For multiple
sites (like you’ve got) it’s recommended to have multiple license servers with
your cals split between them. If your servers are in enterprise mode they’ll
redirect requests to other servers if they’ve ran out of licenses. There’s a
good article on high availability TS Licensing here -

Hi
Im working on a Citrix DR solution for my company. We have 2 sites (Primary
Site and DR Site). Both sites have the relevant server infrastructure incl
Citrix WI servers and XenApp Servers. Primary site has Terminal Server
Licensing server setup in Per user Mode. There is no TS Licensing server in
the DR site. My question is if I lose the Primary site, when users connect to
the DR XenApp Servers they will be trying to contact the TS Licensing server
from the Primary site which will be unavailable. Will the clients be given a
temporary license or will the connection fail?
If no temp licenses are granted then I will install a TS Licensing server in
the DR site and call MS Clearinghouse in a DR scenario to activate. If there
is a better way please let me know
Thanks
