I downloaded the graphical aiccu client for windows. I dumped it into the c:\windows folder. After that I ran it, configured all settings and it created the file aiccu.conf in c:\windows. Everything working ok so far. After that I tried to install it as a service by running it with 'aiccu /i' and it installed itself as a service. It shows up in the Services Control Panel. Now here is where it goes wrong. When I try to start it as a service I get the error 'The SixXS Automatic IPv6 Connectivity Configuration Utility service on Local Computer started and then stopped. Some service stop automatically if they have no work to do, for example the Performance Logs and Alerts Service.' Anyone know what is wrong or what I am doing wrong? I followed instructions on the SixXS website and it runs fine stand-alone just not as a service.
