[Samba] Samba + Windos XP/2k + Netbench Problem

[Herb Lewis]

This may not be a samba problem per se. I just ran a test with a 
single client running 8 engines. 

With clean directory structure - 
Against Win2K server - 2 engines died (1 delete, 1 move)
Against NT4.0 server - 6 engines died (3 create, 3 delete)
Against samba 2.2.4 on IRIX - 6 engines died (1 create, 3 delete, 2 move) 

With old files present - 
Against a Win2K server - 2 engines died (1 create, 1 delete). 
Against NT4.0 server - 5 engines died (5 delete) 
Against samba 2.2.4 on IRIX - 6 engines died (6 delete)

The servers used were as follows 
Win2K - 1P 200 MHz PentiumPro
NT4.0 - 4P 400 MHZ Xeon
Samba - 4P 500Mhz MIPS R14000
