Somehow our whole AAM configuration has gone down the crapper over night and I am scratching my head on how to restore it.
Thoe only configuration present (for the web application at :80) at the moment is
Internal URL | Zone Public | URL for Zone http://portal.domain.com Default http://portal.domain.com
portal.domain.com is the actual public address of the machine. No internal urls are present at the moment and the sites are not reachable except for the Central administration, which is reachable locally.
If I visit a sitecollection on this webcollection on Chrome I get a blank page. If I visit the same address on IE11 I get an http response code 403 forbidden ( but no login prompt)
I've followed Alternate access mappings have not been configured
but to no avail. Please help me out on this one.
