following options when deciding which server to use as the license server:

There are three
types of grace periods provided by Citrix Licensing. Provisioning Services
implements these grace periods as follows:
- Start up license from license
server is 30 days (720 hours): Initial installation of the licensing server
provides start up licenses for all Citrix products. Start up licenses expire
after 30 days. The 30 day count down does not begin until the product prompts
you for the start up license for the first time. Provisioning Services product
licenses must be installed during this period. A start up license for a Citrix
product is voided if a license for that product is installed, regardless of
whether it is valid or invalid.

This grace period may apply in the following scenarios:
- No valid edition licenses for
XenApp, XenDesktop, XenServer, Essentials for Hyper-V or Provisioning Services
are available, and any start up license from the license server have already
been used and are expired.

systems for a period of 30 days. If this grace period lapses, existing target
