We were trying to Migrate our SBS 2003 to SBS 2008. The procedure went fine without any problem until we reached Internet Address management. Here we stuck with the following error message:
“Windows Small Business Server 2008 cannot open port 25, 80, 443 and 987 to the IP address of the server. In order to receive e-mail and other information over the internet, you must manually open those ports.”
I don’t know why the error is saying like this though my ports are open on Fortigate-50B router. Also I am able to access to the internet through this SBS 2008 and other PCs over LAN.
Any idea? Somebody please provide some working solution.
