Hi all

Is there a proper procedure to change the default port no ie 80 in OWA
exchange 2003 to something else say 7500
I want to do the same on my FE server. In the way I would rather open port
7500 on my firewall instead of 80
I tried the above in  exchange 5.5 but am unable to do so in Exchange 2003

thanks

Johnson

Open the Management Console for IIS
Expand the tree view of the server on which OWA is installed.
Right-click the Web site on which OWA is installed, and then click Properties.
Click the Web Site tab.
Change the TCP Port field from 80 to the port you want to use.

I wouldn't change it. I have had nothing but trouble on getting OWA to work correctly on any ports other than 80 and 443.
Remember that OWA is a very complex environment and it has to communicate with Exchange in the proper manner.

If you want to increase the security of your OWA purchase an SSL certificate and open 443.

Security via obsecurity (which is basically what you are proposing) is no security. Anyone wanting to attack your server will just scan the higher ports or sniff the traffic.

I agree with sembee, enabling SSL and running OWA on it would be the best solution.

Hi

Simon I agree that someone would use a port scan.. I was rather thinking on the viruses that normally would attacK port 80.

Yan West : Just a note that I could change the port on my BE server and it works fine. If I try the same on my FE server it does not.




thanks

Johnson

If you are using SSL, why not just close port 80?
If you change the port the clients are going to have to type in http://mail.domain.com:7777 (and it will have to be the full address including the http as the browser will not know that it is a http request).

As I indicated above, I have had nothing but problems changing the port and when it was changed back all the problems went away.
