(each a few hundred Mb) onto different Samba shares. From a W2000
workstation, started another copy of similar directory onto another Samba
share. Everything runs fine for 5-10 minutes, then one of the NT4 copies
hangs with "Unable to copy file ... Session cancelled" or "Unexpected
network error occurred". Typically one or other of the other NT4 copies also
then fails. The W2000 copy always continues OK.

This failure is repeatable, but not on any specific file.

Swapped out NIC but get the same symptoms.

Trawling back through the archives, I see similar reports, particularly when
copying large files, although file size doesn't seem to be a factor here.

The NT4 event log reports "The redirector has timed out a request to Golux"
(the Samba server).

With Samba log level at 3, the last lines report:

My smb.conf is as follows:

Does anyone have any ideas on this?
