Web Proxy/Socks Proxy

When I reboot a WinNT SBS4.5 server the Web Proxy/Socks Proxy/and all other services within the Proxy MMC fail to start.
They fire right up when I right-click and choose ‘start’, but I want then to start automatically.
I checked the “Services” in the Control Panel and the only thing that looked like it might help was making the WWW Publishing Service “Automatic” ( I tried a manual start on this but it did not start the Proxy services).
All other Proxy related services are “Started Automatic”??
Thanks
