Terminal Services licensing and fault tolerance

I have four Citrix Presentation server 4 servers, on Windows 2003 TS. They
are load ballanced(by a network). I am thinking about fault tolerance from a
TS licensing point of view. Currently the Citrix licenses and TS user CALs
are on sever 1.

Lets say server 1 has a hardware failure. I am okay on Citrix licensing, as
the remaining Citrix servers have a 96 hour grace period. What about TS
licensing, is there a grace period?
Would I be better splitting licensing between two servers?

Any suggestions welcomed.
 
Re: Terminal Services licensing and fault tolerance

There's no real grace period for TS Licensing, but in practice,
there is one (sort of..).

Clients start renewing their licenses 7 days prior to the actual
date of expiration. So if all clients connect to the server every
day, you'll have a week to get the server up and running again
before te licenses actually expire.
Clients with a valid (non-expired) license do not need a connection
to the TS Lic4ensing Server at al, because the terminal Server sees
the valid license and doesn't check with the LS at all.

So if your LS goes down, only those clients which haven't connected
for more than 7 days AND have an expired license will be refused,
all other clients will be able to connect.

That said, a second TS LS for redundancy gives your more time and
ensures connection for all clients.

Q. How do I configure Terminal Services Licensing servers for
redundancy or high availability?
