The site configuration screen will list all the web sites that are published under IIS. Web administration can then be installed or removed for each of these sites. The site configuration screen can be accessed via MailEnable Management > Servers > Web admin. Right click and select Properties.
To configure web administration layouts (e.g. base, skin selection, language) by web site requires host headers to be configured.
Right clicking on a host header in the right hand screen under MailEnable Management > Servers > Web admin will then allow the web administration layout to be configured.
