None of the services start because binding to http://+6060/nospamproxy fails

Error:

Without a noticeable reason, the services of NoSpamProxy no longer start. Re-installation does not work. The following error is displayed in the event display:

Log name: System
Source: Microsoft-Windows HttpEvent
Date: 14.03.2012 14:42:55
Event ID: 15005
Task Category: None
Level: Error
Keywords: Classic
User: Not applicable

Description:

The underlying transport for [::]:6060 cannot be bound. The list may contain a reference to an interface that may not be present on this computer for IP listening purposes only. The data field contains the error number.

Status:

This problem occurs in conjunction with IPv6. The “Net TCP Port Sharing” service will then be disconnected. The exact cause is still unknown.

Solution 1:

Enter the following command on the command line:

netsh http add iplisten ipaddress=0.0.0.0

Then the services of the Net at Work Mail Gateway will restart.

Solution 2:

Enter the following command on the command line:

netstat -ano >netstat.txt

Check in the netstat.txt whether a process may occupy port 6060. If this is the case, the corresponding PID (Process ID) is displayed. You can then use task manager to find out to which process the PID belongs. Then it is necessary to clarify whether the process can be adjusted accordingly or not.
