Recently our office resigned its internet and for one reason or another the static IP was changed.
Since then I've been unable to connect any devices to the exchange server outside the network?
We are running SBS 2008 with Exchange 2007.
The root domain i.e. mydomain.co.uk and www.mydomain.co.uk
web hosts are hosted on a seperate server (so is it not possible to use autodiscover in this instance???)
so I have remote.mydomain.co.uk pointing to our server (I have pinged and the correct IP is set).
On the Netgear router incoming HTTP on Port 80 and HTTPS on 443 is forwarded to the server ip.
On the server in Windows firewall I have opened TCP ports incoming on 443 and 80 (also outgoing is this needed?).
When I try and run Microsofts Rmeote Connectivity Test I get the following error;
Testing TCP port 443 on host remote.mydomain.co.uk to ensure it's listening and open.
The specified port is either blocked, not listening, or not producing the expected response.
Any Ideas on how I proceed with this?
