Microsoft Network Environment is not shown between my pix and my users

[darwintovar]

Hi, I have a Cisco Pix 525 (8 network segments) and I have an Active Directory for my users (32.000). I have been configured all netbios and active directory's ports, but I can not see the microsoft network environment (no totality host are shown). I did a test allowing all IP traffic between my servers and my test host, but it wasn't satisfactory. I thought that one was a WINS problem since all the other services of network are normal . I need to know if I must configure something additional or it's a bug in my IOS pix (6.3(3))

thanks for the answer, but already I tried updating to version 7, but I have a problem and is that no of the versions 7.x is compatible with protocols n2h2 to filter content Web, so there I had problems. If he is bug, as he is bug registered? Excuses by my badly English
