Symptoms
- Unable to establish a connection between Confluence server and Sharepoint 2007
- "Basic Connection Test Failed:: Connection refused: connect" error while conducting "test connection" (under the Sharepoint Admin in Confluence)
The following appears in the atlassian-confluence.log:

Diagnosis
- Check the operating system that Confluence server is on. If it is Windows, the "Connection Refused" means Confluence couldn't connect to the Windows NTLM SOAP Proxy started by Confluence. If it is Unix or Mac, need to check on the network and firewall configuration, as Confluence is being prevented from connecting to SharePoint over the network.
Check if something else is using this port by running the following command from a command prompt:
netstat -a -b.

Cause
It looks like the technology we use to run the proxy (.NET's HttpListener) actually required admin privileges to run, because it depends on a sensitive HTTP access library built in to Windows.

Resolution
To grant the Confluence user account permission to bind to the specific IP and Port using the netsh command. Details are here: http://stackoverflow.com/questions/443640/httplistener-start-accessdenied-error-on-vista
