Microsoft Proxy AutoDial does not hang up when the connection is idle.


The Auto-HangUp will fail with any of the following conditions:

  • You have a Winsock application on a client open and connected to the Internet.
  • You have a Web Proxy client (Web Browser) connected to a Web Page that has a refresh tag in it.
  • The active caching of the Web Proxy Service is updating the cache.
  • Other TCP/IP traffic is hitting the modem connection from the Internet.


The Idle TimeOut option in Dial Up Networking must be set for the connection to hang up after being idle.

  1. Open the Dial Up Networking dialog box, and select User Preferences from the More button.
  2. Disable AutoDial by Location and set Idle Seconds Before Hanging Up to the desired amount of time.
  3. Choose Logon Preferences from the More button and set Idle Seconds Before Hanging Up to the same value as User Preferences.
  4. Open Control Panel, Services and disable the Remote Access AutoDial Manager service.
