SYMPTOMS
========
Windows NT, Windows 95, or third-party PPP clients fail to connect to your
Windows NT Remote Access Service (RAS) server using the TCP/IP protocol.
In the System Log of the Event Viewer on your Windows NT RAS server, you see the
following error message:
Event ID: 20091
Source: RemoteAccess
Type: Error
Description: The Remote Access Server was unable to acquire an IP Address from
the DHCP Server to be used on the Server Adapter. Incoming users will be
unable to connect using IP.
CAUSE
=====
This behavior can occur if either of the following conditions exist:
- You are using DHCP on your network, but you have not created an active scope
that includes addresses from the same subnet as the subnet of the RAS
server's network card.
- Your RAS server is configured to use DHCP to assign remote TCP/IP client
addresses (the default option), however, there is no DHCP server on your
network.
RESOLUTION
==========
If there is a DHCP Server on your network, make sure you have an active scope on
your DHCP server that includes addresses from the same subnet as the subnet of
the RAS server's network card. For information on creating and activating scopes
using DHCP Manager, refer to DHCP Help.
If there is no DHCP server on your network, configure RAS to use a static address
pool to assign remote TCP/IP client addresses by performing the appropriate
method below:
Windows NT 4.0
--------------
1. In Control Panel, double-click Network, click the Services tab, and then
double-click Remote Access Service.
2. Click Network, click the TCP/IP check box under Server Settings to select it,
and then click Configure.
3. Click Use Static Address Pool, set the Begin and End addresses, and then
click OK.
Windows NT 3.51 and earlier
---------------------------
1. In Control Panel, double-click Network, and then double-click Remote Access
Service.
2. Click Network, and then click Configure (for TCP/IP) under Server Settings.
3. Click Use Static Address Pool, set the Begin and End addresses, and then
click OK.
