samba - Nov 2003 - very low speed local network browsing from win xp clients

Hi Everyone there!


We have a very annoying problem since several months when browsing the local
network (workgroup) from win xp clients (from win98 clients it's almost OK).
The machines in the workgroup appearing very slooow (about 15-20 sec), and
this value doesn't change even in the 2nd or 3rd browse. We have 1 linux
(debian 2.4.21 pre 3) pc, running the samba (2.2312) server, about 15 win98
clients, 60 win xp clients, 1 win nt server. When I shutdown our win nt
server, the problem doesn't change. When I shutdown our samba server, the
browsing of our workgroup become very fast.

Here is my smb.conf file, perhaps You can help me to solve this problem.
Thank You.

I don't know if it will help, but try changing the settings on the 
Network card of the Windows XP clients.
Go into advanced settings and change "Duplex" from "Auto" to
"Half Duplex".

I have found that samba functions quite badly with Windows clients when 
network packets start getting lost.

You would only need to try the change to "half duplex" on one Windows
XP
client to see if it helps for that one client.

I am still investigating ways to improve samba under these packet loss 
conditions, but it would be nice to see if changing to "half duplex" 
helps others like it helped me.

Cheers
James

Hi,

Suggest you make the changes shown. Let me know how it goes.

Comment out the above 3 lines.

You do not have a WINS server, nor have you indicated that you have
manually set up lmhosts, so do not use them. Use Boradcast first, since
DNS will not help you to resolve NetBIOS names.

It does not help to set this any higher.

Comment out the socket address line.

It's WORKS!!!

Our 1 year problem is no longer exist!!! The speed of browsing our workgroup
is FAAAST now! With Your help and a full server restart the problem is
solved. (I'm very HAPPY now!!!)   :-)

The smb.conf file now:

[global]
;	domain master = no
;	local master = yes
;	preferred master = yes
	passwd program = /usr/bin/passwd %u
	printing = bsd
	syslog only = no
	dns proxy = no
	null passwords = yes
	protocol = NT1
	name resolve order = bcast host
	strict sync = no
;	socket options = TCP_NODELAY IPTOS_LOWDELAY
	character set = iso8859-2
	short preserve case = yes
	printcap name = /etc/printcap
	invalid users = root
	max log size = 1000
	interfaces = 192.168.32.253/255.255.255.0
	debug level = 0
	passwd chat = *Enter\snew\sUNIX\spassword:* %n\n
*Retype\snew\sUNIX\spassword:* %n\n
	preserve case = yes
	security = user
	unix password sync = no
	workgroup = vorosko
	server string = %h server (Samba %v)
	syslog = 0
	client code page = 852
	netbios name = SERVER
	guest account = nobody
	load printers = no
	os level = 33
;	socket address = 192.168.32.253
