[Samba] Windows 98SE can't access Samba

[Paul Neuwirth]

Hello List,
I just upgraded from openSUSE 10.3 to 11.1, had no problems with samba 
until the update (Samba Version should have been 3.0.?). After the 
update (Samba 3.2.4-5.2). Windows 98SE prompted for the password, saying 
it was wrong. Using smbclient id didn't have any problems. Tried around 
enabling/disabling password encryption on both sides, lanman auth, but 
no luck. So i upgraded to Samba 3.4.2-1.1 (suse buildservice, samba 
stable). Now Windows 98SE doesn't even find the server anymore in the 
network neighborhood.
Even accessing by \\IP doesn't work.
Getting following error on connecting of network devices:
The following error occured while reconnecting [...]
Permanent connection not available.
I set the samba logs to max verbosity but getting no entry at all.
No firewall is blocking the network interface.
(Can connect to server port 139 using telnet from windows, getting log 
entrys but also can't access the windows 98SE shares using smbclient 
from the server, but nmap says the netbios-ssn port is open)
All Windows NT based clients work(ed) perfectly with all of the 
mentioned versions.

Here the global part of my smb.conf:
 [global]
 	workgroup = PANE
 	printing = cups
 	printcap name = cups
 	printcap cache time = 750
 	cups options = raw
 	map to guest = Bad User
 	include = /etc/samba/dhcp.conf
 	logon path = \\%L\profiles\.msprofile
 	logon home = \\%L\%U\.9xprofile
 	logon drive = P:
 	usershare allow guests = No
 	add machine script = /usr/sbin/useradd  -c Machine -d /var/lib/nobody -s  /bin/false %m$ domain logons = Yes
 	domain master = Yes
 	netbios name = PANE
 	security = user
 	passdb backend = smbpasswd:/etc/smbpasswd
 	local master = Yes
 	os level = 65
 	preferred master = Yes
 	wins support = Yes
 	encrypt passwords = Yes
 	lanman auth = Yes
	client lanman auth = Yes
 	ntlm auth = Yes
 	log level = all:10

 Thanks for assistance,
 Paul
