[Samba] Problem mounting Win98

[Maxime Quinzin]

  Hello, I have 3 devices, a RH9(with samba) a win98 and a winXP
When I try mounting a win XP directory on my linux, I have :

[root at pcmaster travail]# smbmount //pc-dominique/travail dominique/ -o 
username=dominique,password=dominique
25961: session request to PC-DOMINIQUE failed (Called name not present) ???
[root at pcmaster travail]# ls dominique
2000  AVANT 2000         LES SITTELLES.REN  MONTESQUIEU B.CFG  
MONTESQUIEU B.ETD  MONTESQUIEU C.DEV  test.tst
[root at pcmaster travail]# mount | grep dominique
//pc-dominique/travail on /root/travail/dominique type smbfs (0)

It works but I have a strange failed message.

When I try mounting a win 98 directory on my linux, I have :
[root at pcmaster travail]# smbmount //pc-sasou/travail sasou -o 
username=sasou,password=sasou
25786: session request to PC-SASOU failed (Called name not present)
25786: session request to *SMBSERVER failed (Called name not present)
SMB connection failed
[root at pcmaster travail]# ping pc-sasou
PING pc-sasou (192.168.0.3) 56(84) bytes of data.
64 bytes from pc-sasou (192.168.0.3): icmp_seq=1 ttl=128 time=1.41 ms

It doesn't work, please why ?

I think it's a netbios name problème ... Is there something to do on my 
windows devices ?

Thanks
