Core GIS Server Concepts This is the user that can administer ArcGIS Server. Not a Windows/Linux user (unless you want to)
ArcGIS Server is a pure GIS Web Services Server. All communication for using and administering occurs via http http:6080
ArcGIS Site
GIS Servers live within an ArcGIS Site: a logical grouping of servers that simplifies administration

GIS Server Web browser based management console. You do not need a separate web server to run this
ArcGIS Server Account
ArcGIS Server processes run under this user
Server Directories & Configuration Store Two folders that store key information needed for your server to run. Make sure the ArcGIS Server user has Read/Write access and that folders can be accessed from all GIS Servers
