If you want to stop RAS AutoDial, use control panel / Services. Scan for Remote Access Autodial Manager. Stop it and configure startup as manual. If you want Autodial to work, see KB article Q169244.

If RAS AutoDial tries to dial itself, edit:

HKEY_CURRENT_USER\Software\Microsoft\RAS AutoDial\Address

Scan for your address (both IP and Name) and delete the sub-key. If you have a TCP/IP network, edit:

HKEY_CURRENT_USER\Software\Microsoft\RAS AutoDial\Control, double-click DisabledAddresses and add your IP address on a new line of the REG_MULTI_SZ value.

You must reboot for these registry changes to take effect.
