Using UNC Under Win 3.1 or WfW 3.1 with Long Server Name (100698)
The information in this article applies to:
- Microsoft LAN Manager 2.2
This article was previously published under Q100698 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 Universal Naming
Convention (UNC) name that is longer than 11 characters (for example,
\\twelvecharac\public\edit.com) the system returns immediately with a
dialog indicating that the program/file cannot be found or the path is
invalid. If the server name is 11 characters or less, it functions
correctly.
A Sniffer trace of frames to or from the workstation shows that when the
server name is longer than 11 characters, no attempt is made to access
the network.
CAUSE
The OpenFile() Windows function uses a function internal to the Windows
kernel to check the length of the file name and returns an error if it is
greater than 11.
RESOLUTION
Applications that use the _lopen() function to open a file should not
experience this limitation. Otherwise, you must adjust server name length
or work within the limitation.
