Access Samba share from computer in domain

[mira]

Hi all!

I have a problem with accessing share folder on my home router from my company notebook. This notebook belongs to company domain, but when I am at home, it is not connected to company network. I can see only login dialog with filled field "User name" (there is "172.16.0.1\Guest") that i can't changed (text box is disabled).

When I try to access my share folder from other home computer or I login on my company NB as local user, everything works.

I have ASUS WL-500 GP V2, Oleg's firmware 1.9.2.7-10, Samba 2, Win XP SP3 on all computers.

This is my smb.conf listing:
[global]
workgroup = TDEVELOPX
netbios name = ROUTER
server string = Router
security = SHARE
log level = 1
log file = /opt/var/log/samba/log.%m
max log size = 100
dns proxy = No
guest account = admin
read only = No
guest ok = Yes
hosts allow = 172.16.0.

[share]
comment = Data share
path = /tmp/harddisk/data

Thank you for your advices and suggestions!
