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.

For more information, query on the following words here in the Microsoft Knowledge Base:

direct and hosting



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.5x and 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
