SYMPTOMS
This article describes a situation that may occur with Windows 98 Second Edition (SE) after the installation of Microsoft PPP over ATM adapter. The installation may show one or two extra &quot;adapters&quot; in the Device Manager, which are disabled (a red X over the icon). These extra adapters do not affect the functionality of the enabled adapter because they are disabled and unbound.



CAUSE
This behavior occurs because the Netdi.dll functions default to a maximum configuration for all adapters and then disable those adapters which are not configured by the time the installation gets further into the process. It is not possible for the installer to tell whether or not an adapter will be configured after you restart the computer.



RESOLUTION
If these disabled adapters are either enabled or removed in an effort to clean up the Device Manager, then the subsequent restart removes all of the PPP over ATM adapters and the functionality is gone. You must reinstall the PPP over ATM adapter to re-establish the desired functionality. Therefore, do not remove the disabled adapters.



STATUS
There is no workaround for this issue.



MORE INFORMATION
To duplicate this problem, install some hardware adapter &quot;ATMADAPT&quot; that uses the PPP over ATM functionality, which results in the addition of several protocols. These protocols include: ATM Call lManager->ATMADAPT ATM Emulated LAN -> ATM LAN Emulation Client ATM Lan Emulation Client -> ATMADAPT NDISWAN -> Microsoft PPP over ATM Adapter TCP/IP -> ATMADAPT WAN Support for ATM -> ATMADAPT If you install TCP/IP after you install ATMADAPT, then TCP/IP -> ATM Emulated LAN appears and must be removed in the Network Configuration Wizard. After the system is restarted (required), the System Properties/Device Manager shows (either by type under Network adapters or by connection under Computer) the extra disabled adapters.
