Exchange Webmail Not Working

Hello all,

We are running the Exchange built-in webmail on Exchange 2000, on a Win 2000 server.

We had to reboot this server yesterday, and since then the webmail has not been accessible.

The address of it is:

We get a "The page cannot be displayed" error.

We had rebooted the server because we just installed a new router and fibrebox on our system, which has meant that our default gateway IP address has changed. Will this has screwed things up?

Can anyone please help?!

I am getting server not found.

Is the new ip or the old one?

Is your iis server set to only expect connections on a specific IP Address?

Hello Andrew,

All we have changed is the Default Gateway. The IP address for the webmail has always been

How do I check if the the IIS server is set to only expect connections on a specific IP Address?

If it worked that way before then it should be fine. Is the exchange server able to browse the web?

In fact, I can now ping the server, so I would say that the firewall is blocking port 80.

Can the web server itself get to or http://localhost/exchange?

Thanks Andrew - we have found that since the changes we made, we need to open up port 80 to forward to the IP of our mail server. Once that's done I think we'll be back up and running.
