My citrix server drive failed and I reinstalled Citrix Xenapp 5.0 and Windows 2008. Installed TS licenses and Citrix licenses. However I continue to get a citrix licensing error 501 when logged on as a user and then the session just shuts down. I can log in as the admin account and it says citrix xenapp can not find the license server. I need help! the server has been down for a week now.
