Missing Domain in Microsoft Windows Network

Here is a bit of info on my setup. We are running windows 2000 server with 2000 AD we have 3 domains(Domain1, 2, 3), each with there own DC, DNS server. There is a trust between the domains with Domain1 being the main one. We recently replaced dc1 on domain1 by dcpromo the old one and dc promo the new one and then installed DNS on it. What I notice now is that when I browse through microsoft windows network through network neighborhood on domain1, i can see domain2 but domain3 does not show up. i am able to ping, nslookup and remote into all machines on domain3, just not able to see it through microsoft windows network. Just wondering if anyone has any ideas.

thanks

ok sorry i think you are confused let me clear the clouds
if you have wins server and that is on other domain you need to specify your current details od new domain on to it and you need to make sure that it is talking to wins in order to see your domain ...
hope this ring bells
let us know if any probs

I have fixed the netdiag wins error and that passes, I replicated my sites and was able to see the domain that was missing in windows network, then it all of a sudden disappear. ....I have a silly question why do I need WINS, will I need it when we move to AD2003 will it affect anything during the upgrade?

but inshort its the mother for hosting you mapping doamins if you got more than one well infact even one so you can have external winns server hosted by some other comapany or use the one you have
Hope this will ring bells on my side :-)
