Setup: TCP/IP Binding Defaults To All Installed NIC's (114469)


The information in this article applies to:

  • Microsoft Windows NT Workstation 3.5
  • Microsoft Windows NT Server 3.5
This article was previously published under Q114469

SYMPTOMS

When installing the TCP/IP protocol on a Windows NT version 3.5 Workstation or Server with more than one network interface card (NIC) installed, you are forced to initially bind TCP/IP to every installed NIC. During setup you cannot bind TCP/IP to a single NIC. This is a change in behavior from Windows NT version 3.1.

CAUSE

Under Windows NT 3.1, NetBIOS over TCP/IP (NBT) supported only one adapter, so it would bind to the first adapter. Under Windows NT 3.5, NBT supports multiple adapters and by default the network control panel applet (NCPA) binds all transports to all adapters.

WORKAROUND

If you don't want TCP/IP on a particular segment, go to the network control panel and disable the appropriate TCP/IP bindings.
