If the User Administration module is deployed, then the user trying to access the IGSS server via an Internet browser must authenticate himself with valid user name and password to log on. If the User Administration module is not deployed, then anyone on the intranet with an Internet browser installed will be able to access the IGSS server via the Portal.
To access the Portal from another device, the user must key in the name of the Portal PC followed by the name of the Portal. In the illustration below, the name of the Portal PC, mto_xp, is keyed in first followed by \igssportal.
