Dial-Up Networking Does Not Obtain an IP Address

• Microsoft Windows 95

SYMPTOMS

If you have two or more network adapters in your computer and you are using Dial-Up Networking to connect to a network using the TCP/IP protocol, you may not be assigned an IP address and may not be able to use a static IP address. When this occurs, running Winipcfg.exe shows an IP address and subnet mask of 0.0.0.0, even though you are connected with the TCP/IP protocol.

CAUSE

This problem can occur when you have two or more network adapters installed with TCP/IP bound to each, and you have TCP/IP bound to the Dial-Up Networking adapter.

RESOLUTION

This issue is resolved by the following updated file(s) for Windows 95, and later versions of these file(s):

   PPPMAC.VXD  version 4.00.953  dated 7/9/96  135,288 bytes
   VDHCP.386   version 4.00.952  dated 7/9/96  27,973 bytes 

1. Click Start, point to Settings, click Control Panel, and then double- click Network.



2. Click one of the network adapters. (NOTE: Do not click the Dial-Up Networking adapter.)



3. Click Properties.



4. On the Bindings tab, click the TCP/IP check box to clear it, and then click OK.



5. If you have more than two network adapters, repeat steps 2-4 until TCP/IP is bound to only one network adapter and the Dial-Up Networking adapter.



6. Click OK until you return to Control Panel. When you are prompted to restart your computer, do so.
