That is exactly the problem. The Windows Explorer on the older platforms will try to open files that are shelved. That will bog down the shelving system. > This is the second problem, because WinNT LANMAN server has a pool > of processes and every connection to a LANMAN server got its own > thread.

The reason that the Windows client causes a shelved file to be inadvertantly opened is not important. The number of threads involved is not important to the problem either. SAMBA's being single threaded per process is a totally different issue than the shelved attribute. I can reproduce the problems that you are mentioning simply by putting a CD-ROM changer on a Windows NT system. No network involved at all. If one Explorer window has to wait for the CD-ROMs to switch, all explorer windows will freeze until it is done. -John [EMAIL PROTECTED] Personal Opinion Only
