Renaming the Default Web Site or modifying the Default Web Site on the LANDESK Core Server is not recommended or supported and doing so can break the IIS installation on the core server.
Renaming the Default Web Site will break the IIS Virtual Directories and these will have to be recreated. If they are not recreated correctly and with the correct permissions the LANDESK Core Server will be broken. Typically a reinstall of LANDESK Management Suite/Ivanti Endpoint Manager or a snapshot type restore is needed to fix this issue.
In most cases, the default settings are sufficient for most customer configurations and changes should not be needed.
