Might be a no-brainer, butdo you have any proxy that might be blocking access to that port? The web UI uses regular 80/443, but the admin UI uses 7071. We use a squid proxy here and only allow acess to 80/443. If you use a similar proxy, you need to make sure to configure the browser to NOT use the proxy when accessing that IP/DNS name.

Are you accessing it on the same LAN or network segment? Or, are you trying to access it remotely where NAT might be an issue? If you are able to access it locally, but not remotely, make sure that the firewall/router is routing outbound and inbound traffic via the same WAN IP address. Sometimes, an inbound NAT rule will map 7071 to right internal IP address, but will not route the traffic out through the same link... in this scenario, your local system will throw a fit because it is expecting the traffic from the same IP it sent it to.

Anyhow, I hope some of that helps.

gilly05,

At this point I'm pretty sure it's NAT related. I don't use a proxy. I've tested a few things, and internally on the same LAN as the Zimbra box, it's working fine. Will have to look at the router/firewall a bit more.

Thanks for all your ideas/comments. Greatly appreciated!

if you all havent figured it out by 2010, I just googled it and found this, i just typed loopback in the browser instead of my computer name. that is to say i typed 127.0.0.1 instead
