[Samba] Repost: Samba 3.0.0(2) strange fails at W2k/98, OK at smbclient

[vvp]

Sorry - just repeat the previous one...
 
 Hi everybody,
     I failed to make Samba 3.0.0 /3.0.2a working from Windows side on the 
 slightly different Slackware’s.
     Last try was the “current” Slackware version(kernel 2.4.25) of some
 March 20’s with Samba 3.0.2a in it. Server: Asus P4P800-PIV–RAM 1.5(1)Gb-
 3Com 3C940 integrated. Client(s): W2k SP3, Realtek 8139 NIC.
     Installed OK (binaries from a distribution…), user added OK after
 useradd to Linux. Share path is owned by that user and 'chmod a+rwx'ed.
 Swat works OK except that it always insists that smbd is not running(?). 
 Smbclient was tried at mget/mput Windows distribution (in thousands of
 files), ran at some 6 Mbytes/sec.
     My smb.conf:
 [global]
 	workgroup = WORLD
 	server string = Samba Server
 	log level = 3
 	log file = /var/log/samba.%m
 	max log size = 50
 	socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
 	os level = 64
 	preferred master = Yes
 	hosts allow = 192.168.0., 127.
 [AAA]
 	comment = NO
 	path = /share/AAA
 	read only = No
 	guest ok = Yes
 
     From Windows side I can open shares, list folders, create the
 new ones... but get stuck immediately when trying to make ANYTHING with
 the files slightly larger than few bytes. In fact, it was the same when
 trying to browse large directories (some hundred files). Sure Mr. Gates
 never gives up and keeps trying few times adding new smbd processes and
 file locks...
     Attempts to play with (switching off) locks when I was yet at 3.0.0
 didn't help. Nearly the same was with W98, except that large directory
 browsing was OK.
     I tried to find something in my /var/log/*, but it seems mostly the
 errors at re-connections, re-locks and inabilities to break old locks.
     Could anyone help?
