8 Choose "PPP: Windows NT, Windows 95 Plus, Internet"
from the Dial-up server type drop down box.
9 Check TCP/IP if you are dialing into an ISP for Internet
access.
If you are accessing a remote network, such as a corporate
LAN, check with your MIS network administrator for the
appropriate Network Protocols.
10 Click the TCP/IP Settings button.
In most cases your ISP will provide a dynamic IP address; if so
check "Server assigned IP address" . Enter your DNS and WINS
server addresses if required.
If your ISP has assigned you a dedicated IP address, click
"Specify an IP Address" and enter it here.
11 Click OK to return to the Phonebook Entry screen.
12 Click the Script tab. Set Script to None unless otherwise
specified by your ISP.
13 Click the Security tab.
Change the Authentication method to "Accept any
authentication, including clear text" for PAP authentication or
"Accept Only Encrypted Authentication" for CHAP.
14 Click OK.
The 3C882 ISDN modem does not support Microsoft
Encrypted Authentication. X.25 is not supported either;
therefore, no changes are required on the X.25 screen.
This completes the Dial-Up Networking setup procedure for
Windows NT 4.0. Refer to Chapter 5, "Advanced
Configuration," to review the default settings and ensure that
they reflect your preferences. If you prefer not to change the
default settings, then go on to Chapter 7, "Placing and
Receiving Calls".
