In Windows NT
4.0 you could configure connections to be dial-in/dial-out or both. In

connections

'Accept incoming connections'

Click Next
4. Select
the device which you wish to accept incoming connections on and click Next

5. Select
if you wish to allow Virtual Private Connections and click Next
6. Select
the users who will be able to dial into the connection and click Next
7. Select
the networking components to be enabled for the connection
If you select TCP/IP select it and click Properties. You can then choose if
the connector can talk to the local network and if the address is assigned
by DHCP, one from a list or let the caller set their own address

Click OK
8. Click
Next and give the connection a name and click Finish
To modify the
connection in the future just select from Start - Settings - Network and
Dial-up connections where you can modify the adapters users can connect on,
users who can connect etc.
