The Citrix servers can FUNCTION without contacting the license server and it is 30-days fault tolerant, and in Enterprise version an alert can be set with Resource Manager to send an email in case of License Server Connection FAILURE. If the license server reconnects at any time in the thirty days the problem resolves itself. If the server is not going to come back up, then the license file, DIGITALLY signed with the case-sensitive hostname of the old license server, is the critical COMPONENT. The license file, a *.lic file, can be backed up to a thumb drive SEPARATELY, and restored to a new server with the same name of the old license server, and the Citrix License server software installed.
