DNS settings for OWA behind ISA

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.

Nah, it's not DNS, DNS cannot change the address you type into the address bar.

It's the URLs used in OWA to refer to itself. I suggest you look at the Internal and External URLs for OWA.

hi there

this isn't a DNS issue, it's a server configuration issue

in your exchange management console, open up server > client access
right-click on OWA at the bottom, properties
on the general tab, look at internal/external, and make those be correct

intresting. the client access says it hasnt been modified for over a month.

internal = https://exchangeserver.domain.org/owa (this works internally)
external = https://mail.domain.co.uk/owa

i know you say its not DNS, but should I not perhaps be seeing an entry that would help the ISA in someway pass info to https://exchangeserver.domain.org/owa ?

ISA proxies the connection doesn't it? In which case the use of the name is pretty irrelevant.

That said, we could do with some ISA experts, so I'm going to hook you up to that topic area.

yes i believe ISA listens for the https traffic to mail.domain.co.uk and then forwards it to exchangeserver

sorry for the trouble guys. but have sorted it now. ISA had its knickers in a twist. a quick flush of the DNS and a restart seem to have sorted it out.
Thanks for taking the time to have a look though.
