Run Service

I have a NT Server 4.0 with Proxy Server 2.0 running as a gateway connecting to internet.

The connecting service using a program called PPOE. I try tried to configure the program run at startup

or change the value in registry
HK_local_Machine–>Software–>Microsoft–>Windows–>CurrentVersions–>Run

Question: How can I configure the NT server 4.0 to make the PPOE service connect automatically withouot LOGON.
Thank
