Using UNC with Win 3.1 or WfW 3.1 with Long Server Name

ID: Q98243

The information in this article applies to:

Microsoft LAN Manager, version 2.2

SYMPTOMS

When you attempt to load a document (in Word, Notepad, etc.) or execute a program with the File/Run command from a server with a name longer than 11 characters (for example, \\TWELVECHARAC\PUBLIC\EDIT.COM) by means of universal naming convention (a network path) the system returns with a dialog immediately indicating that the program/file cannot be found or the path is invalid. The problem does not occur if the server name contains 11 or fewer characters.

CAUSE

When the server name is greater than 11 characters, no attempt is made to access the network, as is evident from a Sniffer trace of frames to or from the workstation.

STATUS

Microsoft has confirmed this to be a problem in LAN Manager version 2.2. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
