SUMMARY
=======
This article describes how to configure your computer to use the Point-to- Point
Tunneling Protocol (PPTP) to connect and log on to your Windows NT domain
through a connection to your Internet service provider (ISP).
MORE INFORMATION
================
When you establish a Dial-Up Networking (DUN) connection using PPTP, you are
required to provide a valid Windows NT user name and password. However, when you
provide this user name and password you are not automatically logged on to the
Windows NT domain. If you are not logged on to the Windows NT domain, you may
not have access to some network resources. For example, you may be prompted to
provide a user name and password when you attempt to access a network resource.
In addition, your logon script is not processed when you establish the PPTP
connection.
To log on to your Windows NT domain using PPTP, you must log on to the domain
after establishing the PPTP connection. To do so, use the appropriate method:
NOTE: These procedures assume all of the following conditions exist:
- You have created a Dial-Up Networking phone book entry to connect to your
ISP.
- You have created a Dial-Up Networking phone book entry to connect to your
PPTP server.
- Your computer has a valid machine account on the Windows NT domain.
For additional information about configuring PPTP, see the following article in
