IIS Redirection/Alias

[Jinx_Inc]

Hi

I have setup Server 2003 with Exchange 2003. I can access OWA via https://server/exchange fine. I have created a subdomain and changed the DNS settings to point to my IP Address, this works also. The problem I'm having is if you go http://mail.linusit.co.uk it doesn't work unless I type in http://mail.linusit.co.uk/exchange, I understand why it does this but would like OWA accessible using http://mail.linusit.co.uk.

Any ideas would be very appreciated

Thanks
