Update Message on Administrators Main Page - Error

I am receiving this error on the main page after I login.

The remote file http://updates.bugzilla.org/bugzilla-update.xml cannot be downloaded (reason: 500 Can't connect to updates.bugzilla.org:80 (No such host is known. )).

Either the remote server is temporarily unavailable, or your web server cannot access the web. If you are behind a proxy, set the proxy_url parameter correctly

When I click the link to go to that site I get the following info:

This XML file does not appear to have any style information associated with it. The document tree is shown below.

What is the problem?

Your server is unable to resolve the hostname updates.bugzilla.org which prevents it from downloading the xml file that informs it there are new versions of Bugzilla.

You can change the 'upgrade_notification' parameter if you don't want this file to be downloaded.

I dont believe that to be the case. I am on the server and able to resolve the hostname fine and see the xml file. I was looking at the IIS logs and procmon and no where do I see the request being made to get to that server.

Is there a specific module that does this? Can anyone provide any more information on this?

I believe that the problem may be somewhere with IIS because our old install was Apache and that worked. It could also be with strawberry if there are any perl calls.

Thanks.

Not seeing anything in ProcMon might be expected if RESOLVING the host fails already. I don't think that is reflected in whatever ProcMon is able to monitor. 

The only events which might make sense are settings regarding resolving host names or files like [...]\etc\hosts. But all of that might simply be heavily cached and therefore not recognized by ProcMon.

Bugzilla\Update.pm, especially look at "_synchronize_data". Looking at the code, it seems that a proxy is ALWAYS considered, so check your IIS-environment for any proxy-related settings. Those would take effect when running Bugzilla.

The workes running Bugzilla in IIS might be firewalled or something like that as well.
