Problem Cause
When changing the static IP address of a server the applications fail to launch. One of the causes for this issue is that the httpd.conf file on the XenApp server is not updated with the new IP address of the server. The httpd.conf file is used by the Citrix XTE Server service for Session Reliability. If this file does not contain the correct information, applications fail to launch.Issue/Introduction
