Unable to browse parent domain from child domain

I have two domains, parent and child. I can browse from parent to child and see all servers and clients in both domains. But I can't browse from the child server, or a child client, to the parent domain. I can connect explicitly to services in the parent (\\server\share). WINS in the child domain has all the records for the parent domain (this is all Windows Server 2003 and XP, I only installed WINS to see if it would resolve this problem). Two-way trusts exist between the two domains. NetDiag and DCDiag show no problems on either parent or child domain. DNS all appears to be fine.

Anyone got any ideas?

Problem solved itself. I had not waited long enough for WINS to kick in. Now all devices on child domain can see parent.

Still none the wiser as to why parent could always see child even without WINS, but it works, so who's complaining!

If computers are on the same segment or ARP Broadcast Domain, they will populate the Segment Master Browser and therefore be browsable by all clients on the segment(subnet).

If you are using multiple subnets, then your Segment Master will need to use WINS(or LMHOSTS) to locate the Domain Master Browsers which are designated with <1B> records.

Browsing gets complicated, but I'm glad you got everything worked out.  Post a question in CS to get your points refunded.
