Read Only Patch for AutoCAD Release 14.01 accessing Unix Servers
If you open a drawing file on a remote network drive using AutoCAD Release 14, AutoCAD displays a warning message stating that the drawing is in use or is read-only. Although neither of these conditions exists, the drawing cannot be edited. This problem occurs primarily on third party file servers that use the SMB redirector network interface. On occasion, this problem has also occurred using Windows NT/95/98 servers.
This patch resolves an operating system timing conflict that the third party file server interprets as a file sharing violation. At this time, Microsoft does not have a definitive explanation for the cause of this problem. By changing which calls AutoCAD makes during save operations, this timing conflict is eliminated. This patch works only on AutoCAD Release 14.01.
