We publish our OWA through our ISA2004 server.
Out exchange server is MS 2007.
We can browse to the OWA website on the internet. But after typing in our username/password we get a DNS error. Telling us to try the internal address, (this obviously works for people inside the company but not for external people)
I know someone has been messing with the DNS but no one will own up! So now its up to me to work out whats going on.
So for example out external OWA being https://mail.domain.co.uk/owa
try and login, get the DNS error, points us to http://exchangeserver/owa
In DNS currently there is a Host(A) record for exchangeserver to its IP and a corisonding PTR. Am guessing I may need to create a CNAME or Host(A) to point mail.domain.co.uk at the exchange server?
Any help would be appreciated.
