The Access Ramp TSRs are installed as part of IP Insight software (can't remember the software maker). You can decline to install IP Insight during Winpoet setup, or go into Add/Remove programs uninstall IP Insight by hand if it's already installed. It really doesn't do a darn thing for you.

This will not affect the user's ability or inability to access their DSL service."

Renaming the extension of ARUCfg32.exe to ARUCfg32.exe1 works. The ARUpld32.exe is not loaded when launching the dial up client.
