How to connect QNAP TS-119 NAS on Kuibuntu 10.04

I have purchased QNAP TS-119 NAS last few days. In Kubuntu system, I install Samba for file sharing. The problems are as follows:-

1) Click computer > network > Samba Share > Nas... I cannot see the QNAP NAS located at the folder.
2) I have disabled the UFW/firewall and the NAS is still not listed at Samba Share folder.

Is there anyone who can advise me how to configure the Samba to access the NAS.

Thanks !!!
