Citrix

Change the License Server in XenApp 6.5

In order to change the Citrix licensing server you need to update the Citrix Computer Policy as well as change two registry entries. Updating the Citrix Policy does not update the registry keys automatically which means if the server is unable to contact the Data Store during a reboot it will revert to these keys, and if they are not correct you will get licensing errors upon logon.
  1. Update the Citrix Computer Policy value for ‘License Server Hostname’
  2. Change the value of the following two registry keys to include the new server name

1 HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlCitrixLSName
2 HKEY_LOCAL_MACHINESOFTWAREWow6432NodeCitrixLicensingMFCM_LSHostName
