Problems Installing Network Protocol That Uses TDI Interface

• Microsoft Windows 95

SYMPTOMS

Windows 95 may stop responding (hang) with different results on different Computers when you try to install a network protocol that uses the TDI interface.

This problem occurs only if the Microsoft TCP/IP protocol is already installed when you try to add the other protocol, or when you try to add the Microsoft TCP/IP protocol after installing another protocol that uses the TDI interface.

CAUSE

The TDI interface provider (Vtdi.386) included with Windows 95 supports only one protocol using that interface. The TCP/IP protocol included with Windows 95 uses the TDI interface, causing a conflict if you install an additional protocol that uses the TDI interface.

RESOLUTION

This issue is resolved by the following updated file for Windows 95, and later versions of this file:

   VTDI.386  version 4.00.951  dated 12/4/95  5,711 bytes
