Fault condition: The modem entries “NDIS WAN Line 1”
and “Line 2” are not displayed in Dial-Up Networking,
or a message appears upon starting Dial-Up Networking
prompting you to install a modem.
Possible cause: You have not followed the installation
sequence exactly (see Section13.1.2).
Solution: Remove all components already installed (Di-
al-Up Networking, NDIS WAN CAPI driver) and begin the
installation again with Dial-Up Networking (see Section
13.1.2.2).
13.2 Using NDIS in Windows NT 4.0
The NDIS WAN CAPI Driver for Windows NT enables the use of
Remote Access Services (RAS) over ISDN. NDIS is an abbrevi-
ation for Network Device Interface Specification, and repre-
sents a standard for binding network adapters (hardware) to
network protocols (software). NDIS WAN is a Microsoft exten-
sion of this standard for Wide Area Networking (WAN). The
NDIS WAN CAPI Driver for Windows NT thus allows the ISDN
adapter to be used as a WAN adapter, addressed through
the Common ISDN API (CAPI) 2.0 applications interface.
Please install the software according to these instructions.
You should also refer to the Windows NT documentation per-
taining to Remote Access Services (RAS).
