SYMPTOMS
========

A DHCP server has active leases for Remote Access Service (RAS) servers, but
there are no RAS servers running on the network.

NOTE: You can tell that the addresses are for RAS by the telephone icon in the
active lease window.

CAUSE
=====

When the RAS servers configured to use TCP/IP were previously active, they
received leased IP addresses from the Dynamic Host Configuration Protocol (DHCP)
server. When the RAS servers were configured to only allow users to dial out
those leased IP addresses were not deallocated by the DHCP server.

There were Remote Access servers installed (configured to Receive calls and to
dial-out) and configured for TCP/IP at one time, and they were allocated
addresses by the DHCP server, but they were changed to dial-out only through the
NCPA.

RESOLUTION
==========

1. Start Registry Editor and go to the following subkey:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
  \RemoteAccess\Parameters\IP

2. To delete the IP key, choose Delete from the Edit menu.

Be sure that the only key that appears under the Parameters key is the
NetbiosGateway key.

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 3.51. We are
researching this problem and will post new information here in the Microsoft
Knowledge Base as it becomes available.
