Linux can't telnet to WFW 3.11

[Ulung Pribadi]

My server is RH 5.2 and i use Samba 1.9.18p10 and the client use WFW 3.11 with
tcp/ip protocols installed. The subnet and the IP Address is right but I still
only telnet form WFW 3.11 to Linux...not the reverse. On Linux telnet is
working. I've checked it  through this cmdline "telnet localhost 23 or telnet
127.0.0.1" . And I also testparm smb.conf and nothing wrong happen. FYI I set
smb.conf like this : 

[global]
WORKGROP = XXXX
hosts allow = XXX (my ip and WFW 3.11 ip)
printcap name = /etc/printcap
load printers = yes
printing= bsd
logfile = XXXXX
max log size = 50
security = user
localmaster =no

[homes]
comment = Home Directories
browseable = yes
writable = yes

It's been a long exhausted day .
Please help me and what change should I make...
