Windows 95 Clients Connected to NT Server over NWLink May Fail

• Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0
• Microsoft Windows NT Server versions 3.5, 3.51, 4.0
• Microsoft Windows for Workgroups version 3.11
• Microsoft Windows 95

SYMPTOMS

Applications on Windows 95 or Windows for Workgroups 3.11 may fail while writing data to a computer running Microsoft Windows NT server over the NWLink protocol. The problem occurs only when direct hosting over NWLink is used. Direct hosting is a method of bypassing the NetBIOS layer and sending client/server message blocks (SMBs) directly over the NWLink protocol.

When the problem occurs, the application on the client computer may display the following message:

Error 55: The specified network resource or device is no longer available.

WORKAROUND

The workaround involves disabling direct hosting. To turn off direct hosting, disable the NWLink IPX/SPX binding in Windows NT Server service. After this is done, enable NWLink with NetBIOS on the client computer.
