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.



SYMPTOMS
When you install an additional network interface card (NIC) and Routing and Remote Access Service (RRAS) is already installed, you receive the following error message in the System Log in Event Viewer:

  Event ID   : 20101 Source    : Router Type      : Warning Description: Using the default value for Registry parameter Enabled because the value given is not in the legal range for the parameter.

This event will be logged every time RRAS starts yet does not prevent RRAS from starting properly, nor does it cause any loss of functionality within RRAS.



CAUSE
When the new NIC binds to the Router Service in the registry, an incorrect value is set for the interface's Enabled value.



RESOLUTION
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.

To work around this issue, perform the following steps:


 * 1) Start Registry Editor (Regedt32.exe), and go to the following subkey:

NOTE: The above registry key is one path, it has been wrapped for readability.
 * 1) Modify the value to "1". The value (x) will vary with the number of installed network interfaces. Verify each (x) has a valid "Enabled" value of "0" or "1".


 * 1) Quit Registry Editor and restart your computer.



STATUS
Microsoft has confirmed this to be a problem in Routing and Remote Access Service for Windows NT Server 4.0. We are researching this problem and will post additional information here in the Microsoft Knowledge Base as it becomes available.
