SYMPTOMS
When you use the Novell NetWare Windows utility, Nwuser.exe, to send messages to and from Novell clients, the message is truncated to approximately 38 characters (NWUSER permits up to 255 characters.) This behavior is different than the Novell DOS client's Send.exe utility, which permits only up to 55 characters.
