Suddenly, the company web cannot be accessed from outside the network and we can only receive emails internally. We can send out emails to external contacts, but cannot receive mail from them.
The companyweb can be accessed from within the network.
Here is our setup.
Microsoft Small Business Server 2003
Our ISP is Time Warner, Road Runner.
Our account is setup as DHCP.
The server has two nic cards, one for broadband is connected to Time Warner modem, the other to the network switch.
The server is using a software from Dynamic DNS that updates their host file with the new IP whenever it is changed. I have verified that it is up to date. I pinged the domain and receive a response from the IP currently assigned.
I have verified that the websites in IIS are running.
Not sure where to start troubleshooting.
