Windows NT Multi-site Licensing question

[APT SA]

We have a multi-site environment with our Citrix-TS servers in the HQ site.
We are planning on deploying a distributed TS application that would run in
the remote sites. I wanted to put license servers in the remote sites so
they would get their licenses in their own sites. This will be fine when
connecting to distributed app in their site but will it affect their access
when they connect to TS app in HQ office. In other words if you have TS and
license server in site 1 and client and license server in site 2, if client
connects to site 1 will it have to pull CAL over WAN and/or will it attempt
to get a new license from license server in site 1 even though site 2 already
issued one? I hope this makes sense.

Actually, no
I don't understand where your Terminal Servers are going to be
located, all in HQ, or also in the sites?

But keep in mind that clients never communicate directly with a TS
Licensing Server. All licensing traffic is between the client and
the TS and between the TS and the TS LS. The TS request a TS CAL
from the TS LS on behalf of the client and forwards it to the
client. So your TS Licensing Servers should be on the same subnet
as the TS to avoid WAN traffic.

If a client already has a valid TS CAL, it will not receive another
one, irrespective of which TS it connects to.

Does this answer your question?

All devices are in the same domain. Terminal servers are located in both
sites. Client1 in site1 connects locally to TS1 in site1 and gets license
for LS1 in site1. The next day client1 needs to connect to TS2 in site2
which has LS2 to hand out licenses. Now my question is does TS2 now pull
license over WAN from LS1 or does it go to LS2 and issue another license or
does something else happen?

As Vera stated, if a client gets a license today and connects to
another TS tomorrow then the license is still valid and no
communication with the TS LS is necessary.

I hope this answers your question.

How can this be? I thought everytime the client connects the TS has to
contact License server to insure license. If no license server is available
then your SOL..Right? Isn't that why they recomend 2 license servers?

No, not at all.
When a client connects to a TS, the TS checks if the client already
holds a valid license. If it does, the TS doesn't contact a TS
Licensing Server at all.
So if your LS goes down, there's no immediate problem for clients
that hold a valid license. There's only a problem for new clients,
and for those who must renew their license.
