Can't see samba server from Win98 machine

Dear sirs,

I have a problem with samba: 2 computers on the smalest
network possible, and the Win98 can't browse the
Linux-Samba shares.

I read the DIAGNOSIS.txt from samba distributions and the
testing is the same as in the Blair book. DOES ANYONE
BOTHER TO ACTUALLY READ MY TESTING?!? Using security=server
as Daniel Tan suggested didn't change anything.

I followed the 10 steps diagnosing procedure from John D.
Blair's book "Samba - Integrating UNIX and Windows" [same
as DIAGNOSIS.txt]:

1) testparm gave the following result [this may give an
overview about smb.conf settings]:

Load smb config files from /etc/samba/smb.conf
Processing section "[tmp]"
Processing section "[c]"
Processing section "[d]"
Processing section "[public]"
Loaded services file OK.

# Global parameters
[global]
	coding system = 
	client code page = 850
	workgroup = STANDALONE
	netbios name = 
	netbios aliases = 
	netbios scope = 
	server string = Samba Server
- - - - [cut all those lines...] - - - - - - - - -
	fake directory create times = No

[tmp]
	comment = Temporary file space
	path = /tmp
	guest ok = Yes

[c]
	path = /mnt/win95
	guest only = Yes
	guest ok = Yes

[d]
	path = /mnt/w95ext
	guest only = Yes
	guest ok = Yes

[public]
	path = /mnt/w95ext/public
	writeable = Yes
	guest only = Yes
	guest ok = Yes

2) Both computer can 'ping' the otherone either as IP
address or by host name [included in hosts].

3) smbclient -L NKHOME -U '' -N (smbd running and
accesible) gives:

added interface ip=10.0.0.1 bcast=10.255.255.255
nmask=255.0.0.0
Domain=[STANDALONE] OS=[Unix] Server=[Samba 2.0.7]

	Sharename      Type      Comment
	---------      ----      -------
	tmp            Disk      Temporary file space
	c              Disk      
	d              Disk      
	public         Disk      
	IPC$           IPC       IPC Service (Samba Server)

	Server               Comment
	---------            -------
	NKHOME               Samba Server

	Workgroup            Master
	---------            -------
	STANDALONE           NKHOME

Also the ps -aux | grep smbd shows the daemon running:

root       642  0.0  0.4  3892 1268 ?        S    19:43  
0:00 smbd -D
root      1285  0.0  0.2  1620  592 pts/1    R    20:04  
0:00 grep smbd

smbclient -L MELINTE -U '' -N (on the other host) correctly
shows the shares on the Win98.

4) nmblookup -B NKHOME __SAMBA__ [nmbd running] returns:

querying __SAMBA__ on 127.0.0.1
10.0.0.1 __SAMBA__<00>

Also ps -aux | grep nmbd shows the output:

root       647  0.0  0.5  3252 1380 ?        S    19:43  
0:00 nmbd -D
root      1289  0.0  0.2  1620  592 pts/1    R    20:04  
0:00 grep nmbd

5) The client's NetBIOS name can be resolved:

nmblookup -B MELINTE '*'
querying * on 10.0.0.2
10.0.0.2 *<00>

6) Broadcast address correctly determined:

nmblookup -d 2 '*'
added interface ip=10.0.0.1 bcast=10.255.255.255
nmask=255.0.0.0
querying * on 10.255.255.255
Got a positive name query response from 10.0.0.2 ( 10.0.0.2
)
10.0.0.2 *<00>

What looks odd here is that the linux [10.0.0.1] doesn't
seem to respond (none of the commands issued).

7) User authentication seems to work:

smbclient '\\nkhome\tmp'

added interface ip=10.0.0.1 bcast=10.255.255.255
nmask=255.0.0.0

Also it works on the Win98:

And I also can smbmount the Win98 shares without problems.

8) nmbd does not respond to the PC:

net view \\nkhome [on Win98] ends in:

Error 59: An unexpected network error has occurred. Quit
all running 
programs, restart your computer, and then try again. If the
problem persists, 
contact your network administrator.

meanwhile, tcpdump on the Linux shows:

It seems that netbios-ssn does not respond, but:

netstat -a | grep netbios
tcp        0      0 *:netbios-ssn           *:*

shows the service as listening...

Can anyone help me with all this mess?!?

Thanx,
