SSL OWA only externally - 7.Dec.2006 9:09:14 AM

Hi,
I have a single Exchange 2k3 SP2 from which OWA is securly published through ISA 2k4 SP1. OWA was configured according to Tom's article (great job Tom.) However, I have a problem here:
1 - It only works for external users. Users on the LAN get "Error Code: 502 Proxy Error. The ISA Server denied the specified Uniform Resource Locator (URL). (12202)" error. I confirm that the listener includes both networks.
2 - Any article on how to modify the FBA dialogue so that users do not have to type the domain name?
Thanks
Yba

Hi Yba,

You can configure the internal interface to listen on the OWA WPR's Web listener.

Then configure a split DNS entry so that internal users connect to the internal interface to reach the OWA FQDN.

HTH,
Tom

Hi,
OWA to FQDN already works fine. For OWA to cert common name for internal users, isn't the entry in ISA HOSTS file mapping cert common name to internal OWA site IP enough?

Thanks
Yba

Hi Yba,

No, you need to configure the split DNS entry.

HTH,
Tom
