The information in this article applies to:

- Microsoft Windows NT Server versions 3.51, 4.0 
- Microsoft Windows NT Workstation versions 3.51, 4.0 
- Microsoft Windows 95 
-------------------------------------------------------------------------------

SYMPTOMS
========

If you use Dial-Up Networking (DUN) on your computer running Windows 95 to
connect remotely to a Windows NT RAS server, then you may be able to ping the IP
address of a host on the remote LAN, but you cannot successfully ping the remote
host by name. Pinging the host name generates the following error:

  Bad IP Address <host name>

Browsing functionality in File Manager and the NET VIEW \\<hostname>
command still work correctly.

CAUSE
=====

You still have a network adapter installed on your Windows 95 Dial-Up Networking
client computer, and the TCP/IP protocol is bound to this adapter.

In addition, you may have the following configuration options selected:

- The "Obtain an IP address automatically" option is selected on the IP Address
  tab when you select TCP/IP and then click Properties in the Control Panel
  Network tool. And on the WINS Configuration tab, you have the "Enable DNS for
  Windows Resolution" option selected.

- In TCP/IP Settings for the DUN connectoid, you have the "Server assigned name
  server addresses" option selected.

RESOLUTION
==========

On the Windows 95 DUN client, perform one of the following:

- Use the Windows 95 Hardware Profile feature to create a remote hardware
  profile that eliminates the network adapter on the Windows 95 DUN client
  computer.

  NOTE: If you are using a laptop with a PCMCIA NIC and modem combo PC Card,
  then you can disable the Network Adapter functionality separate from the
  modem functionality without removing the entire PC Card from the remote
  Hardware Profile.

-or-

- Use the "Release All" option in the Winipcfg.exe utility to release all IP
  addresses bound to the network adapter.

-or-

- Enable Domain Name System (DNS) name resolution on the Windows 95 DUN client
  and specify a DNS server in the DUN connectoid that can resolve the ping for
  the remote host name.

MORE INFORMATION
================

The Windows 95 DUN client was connected to a LAN through the network adapter,
and a Dynamic Host Configuration Protocol server on that LAN assigned a WINS
server address to the Windows 95 client. Now that the client is no longer
connected to the LAN, the WINS server is no longer reachable because this WINS
server does not exist on the remote network.
