A Windows server that hosts the Manager Service component must meet additional requirements, in addition to those for all IaaS Windows servers.
The requirements are the same, whether the Manager Service host is a primary or backup.
No firewalls can exist between a Manager Service host and DEM host. For port information, see IaaS Windows Server Ports.
The Manager Service host must be able to resolve the NETBIOS name of the SQL Server database host. If it cannot resolve the NETBIOS name, add the SQL Server NETBIOS name to the Manager Service machine /etc/hosts file.
Configure Internet Information Services (IIS) according to the following table.
You need IIS 7.5 for Windows 2008 variants, IIS 8 for Windows 2012, IIS 8.5 for Windows 2012 R2, and IIS 10 for Windows 2016.
In addition to the configuration settings, avoid hosting additional Web sites in IIS. vRealize Automation sets the binding on its communication port to all unassigned IP addresses, making no additional bindings possible. The default vRealize Automation communication port is 443.
