help with accessing reportserver with web browser

I am using sql express w/ advanced services on xp pro with IIS 5.1 installed. On the local machine named 'Tester' i am able to access reportserver using a web browser and the url: http://localhost/reportserver. But when i go to another machine on the same network and domain and try to access the reportserver with url: http://Tester.domain/reportserver or http://<ip address of Tester>/reportserver ie tells me page cannot be found and does not give me any errors. How do I set up network access to reportserver on the machine Tester? Help would be greaty appreciated.

Try and turn off Windows Firewall to see if that helps.

To troubleshoot, you should be able to telnet to port 80 from the other machine.

cheers,

Andrew
