Proxy can't auto-disconnect

I have MS Proxy2.0 in NT4.0 Server configured for dial on demand. It can auto-dial no problem but occasionally it won't disconnect. I've tried setting it to various time, but sometime it still won't disconnect. I use the dial-up monitor to check that the connection is totally idle. Can somebody offer me some tips?

Many thanks in advance.

Troubleshooting Proxy 2.0 RAS Autodial and Autodisconnect
Last reviewed: February 19, 1998
Article ID: Q181407
The information in this article applies to:
Microsoft Proxy Server, versions 1.0, 2.0
IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

Microsoft Proxy Server has the ability to autodial a RAS phonebook entry to connect to the Internet when a proxy request is made.

This article describes troubleshooting steps required for RAS autodial and autodisconnect to function correctly with Microsoft Proxy Server 1.0 and 2.0.

Please see "Setting Server Parameters" in the Microsoft Proxy Server documentation for complete Setup instructions before consulting this article.


To Disable RAS Autodial Manager:

In Control Panel, double-click Services.
2. In the Services dialog box, select Remote Access Autodial Manager, and
   click Startup.
3. In the Service dialog box, under Startup Type, click Disabled, and then
   click OK.

To Enable Connection Manager:

In Control Panel, double-click Services.
2. In the Services dialog box, select Remote Access Connection Manager, and
   then click Startup.
3. In the Service dialog box, under Startup Type, click Automatic, click
   OK, and then click Close.

If a prefix is required to reach an outside line, it must be manually pre- pended to the phone number in the RAS phonebook. The telephony settings are not imported when using the RAS API.

Dialing Behavior:

Proxy Server 2.0 has changed the dialing behavior slightly. You can modify the registry to revert to Proxy Server 1.0 dialing behavior by doing the following:

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

Start the registry editor.
2. Create the following registry value:


   Value Name: DialFailFailsConnect
   Data Type:  REG_DWORD
   Data:       0 (Decimal)

A value of zero (0) reverts to Proxy Server 1.0 behavior. A value of one (1) specifies the new behavior in Proxy Server 2.0.

RAS will fail to disconnect under any of the following conditions:

- A Winsock application on a client is open and connected to the Internet.

- A Web Proxy client (Web Browser) is left open and connected to a Web Page

   that contains a refresh tag.

- The active caching feature of the Web Proxy service is updating the

- Other TCP/IP traffic is present on the modem connection from the
   Internet. For example, some Internet service providers may send router
   messages (such as ICMP or IGMP messages) to your server while it is
   connected to the Internet. A network trace utility such as network
   monitor can be used to verify that this is the cause of the problem. It
   may be necessary to contact your Internet service provider to correct
   this problem.

Other Settings That May Affect Autodisconnect:
PPP LCP extensions should be disabled to prevent LCP packets from resetting the autodisconnect timer. To disable, edit the phonebook entry for your connection. On the Server tab, clear the check box for Enable PPP LCP Extensions.

To Unbind the WINS Client from External Network Adapters:

In Control Panel, double-click Network.
2. In the Network dialog box, click the Bindings tab. 3. Next to Show Bindings for, click the down arrow, and then select all
4. In the adapter list, click the plus sign next to Remote Access WAN
   Wrapper to expand the view.
5. Under Remote Access WAN Wrapper, select WINS client (TCP/IP), and then
   click Disable.
6. When finished, click OK.
To Set Idle TimeOut:

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

Open the Dial Up Networking dialog box, and select User Preferences from the More button.

Disable AutoDial by Location, and set Idle Seconds Before Hanging Up to the desired amount of time. This value should be greater than 60.

Choose Logon Preferences from the More button, and set Idle Seconds Before Hanging Up to the same value as User Preferences.

Open Control Panel/Services and disable the Remote Access AutoDial Manager service. (See top of this article.)

Good Luck

i had the same problem.
i instaled Network Monitor,
and i found that my ISP was sending me RIPs  (routing information protocol) every 30 second , so my modem did not retch
to the configure idle time.
the source of the RIPs was the RADIUS software on the ISP
