Samba: Network Route was not found
 

Assalam o Alaikum!
After configuring and starting service of samba, when I access shared folder from windows XP it gives this error " Network Route was not found".
My server IP 192.168.1.252, client is on same network.

selinux is disabled
smb,conf:


workgroup = WORKGROUP
server string = Samba Server Version %v

; netbios name = MYSERVER

interfaces = eth0 192.168.1.252/24
hosts allow = 127. 192.168.1.



security = share
passdb backend = tdbsam

[share]
comment = All users
path = /mnt/share
browseable = yes
writable = yes
guest ok = yes
valid users = root uk
share modes = yes

above problem is resolved. Now I have new problem. When I access from windows XP to linux through samba server it prompts for (GUI):
User name: 192.168.1.10\Guest
Password :

and 192.168.1.10\Guest can't change (it is grayed), I do not make any user with name Guest. I want to access with user either root or uk but unable do to that.

Note: I have done this smbpasswd -a uk
